This study deals with control of the mol. weight and mol. weight distribution of poly(vinyl acetate) by iodine-transfer radical polymerization and reversible addition-fragmentation transfer (RAFT) emulsion polymerizations as the first example. Emulsion polymerization using Et iodoacetate as the chain transfer agent more closely approximated the theor. mol. weights than did the free radical polymerization Although ¹H NMR spectra indicated that the peaks of α- and ω-terminal groups were observed, the mol. weight distributions show a relatively broad range (M_w/M_n = 2.2-4.0). On the other hand, RAFT polymerizations revealed that the dithiocarbamate 7 is an excellent candidate to control the polymer mol. weight (M_n = 9.1 × 10³, M_w/M_n = 1.48), more so than xanthate 1 (M_n = 10.0 × 10³, M_w/M_n = 1.89) under same condition, with accompanied stable emulsions produced. In the M_n vs. conversion plot, M_n increased linearly as a function of conversion. We also performed seed-emulsion polymerization using poly(nonamethylene L-tartrate) as the chiral polyester seed to fabricate emulsions with core-shell structures. The control of polymer mol. weight and emulsion stability, as well as stereoregularity, is also discussed. © 2012 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem, 2012.

Photopolymerization of styrene using benzyl N,N-diethyldithioaminoformate (BDC) as iniferter was studied. Both the yield and average mol. weight of the polymer increased with increasing polymerization time. Polymers with functional end groups were obtained. During the polymerization, the stable small radical which was produced by photolysis of BDC or functional end groups and the propagating radical of styrene were determined by ESR. The living radical polymerization mechanism was explained.

The effects of reaction medium (alc., dioxane, dioxane/alc.) on the heterogeneous polymerization of acrylamide initiated by BDC (benzyl diethyldithiocarbamate) were studied. Heterogeneous polymerization differed from homogeneous solution polymerization initiated by BDC and did not have the character of living radical polymerization The polarity of reaction medium affected the enolization of acrylamide. The polymer yield and polymer mol. weight had different values using different solvents. The UV spectra showed that iniferter functional groups remained in products.

Kyeremateng, S. O. published the artcileTriphilic block copolymers: synthesis, aggregation behavior and interactions with phospholipid membranes, Name: Benzyl diethylcarbamodithioate, the publication is ACS Symposium Series (2010), 65-84, database is CAplus.

Novel PPO-based amphiphilic diblock copolymer and triphilic multiblock copolymer analogs of the architectures BA, CBA, and CABAC have been successfully synthesized by combination of atom transfer radical polymerization (ATRP) and copper(l)-catalyzed alkyne-azide cycloaddition (CuAAC) ‘click’ post-polymerization reaction. The A, B, and C components of the block copolymers are formed by hydrophilic poly(glycerol monomethacrylate) (PGMA), lipophilic poly(propylene oxide) (PPO), and perfluoroalkyl segment, resp. Their critical micelle concentrations in water are determined from surface tension measurements. Their aggregation behavior in aqueous medium is studied by temperature-dependent ¹H- and ¹⁹F NMR spectroscopy. The presence of the perfluoro segments within the micelle cores of the triphilic block copolymers enhanced 3-4 folds their solubilization capacity of tetrafluorobenzene compared to micelle cores without the perfluoro segments. It is found that the triphilic copolymer inserts into lipid membranes and induces lateral demixing between the two homolog lipids at of the phase transition of the lipids.

A polymer supported diethyldithiocarbamate anion reacts with primary and secondary alcs. via their trifluoracetates giving alkylated diethyldithiocarbamates in good yields. For example, a solution of benzyl alc. in dichloromethane was added trifluoroacetic anhydride. The trifluoroacetic acid thus formed was evaporated together with the solvent and the residue (benzyl trifluoroacetate) was diluted with acetonitrile and added to Amberlite IRA-400-supported N,N-diethyldithiocarbamate and the mixture was stirred at 25° for 5 min. The resin was removed by filtration and the product, diethylcarbamodithioic acid phenylmethyl ester, was obtained in 84% yield.

Dutta, Soumya published the artcileIodine mediated direct coupling of benzylic alcohols with dithiocarbamate anions: An easy access of S-benzyl dithiocarbamate esters under neat reaction condition, Recommanded Product: Benzyl diethylcarbamodithioate, the publication is Tetrahedron Letters (2020), 61(41), 152382, database is CAplus.

An efficient, metal and solvent free synthesis of S-benzylic dithiocarbamate esters has been demonstrated via the iodine mediated direct C-S coupling of benzylic alcs. with dithiocarbamate anions generated in-situ by the reactions of amines and carbon disulfide. All the reactions were very fast (15-30 min) and performed under open air atm. Cyclic and acyclic secondary amines, primary amine, aromatic amine actively participated in the one-pot coupling reactions with different benzylic alcs. Non benzylic alcs. offer the synthesis of O-thiocarbamate compounds under the identical reaction condition.

Some comblike terpolymers composed of Me methacrylate (MMA), methoxypolyethyleneglycol methacrylate (MPEGMA) as a hydrophilic component, and methoxypolypropyleneglycol methacrylate (MPPGMA) as a hydrophobic component were synthesized by both living radical photopolymerization and ordinary radical polymerization Since these terpolymers showed a high surface activity, it was suggested that they could be utilized as good polymeric emulsifiers. The polymeric emulsions containing these emulsifiers also showed comparatively good emulsion and mech. properties as an adhesive. From these facts, it was found that these terpolymers had almost the same emulsification capability as com. available low mol. weight emulsifiers. Conversely, a difference in surface tension behavior of these terpolymers could be observed It was due to the chain arrangements (random or block sequence) of the terpolymer.

Mayadunne, Roshan T. A. published the artcileLiving Radical Polymerization with Reversible Addition-Fragmentation Chain Transfer (RAFT Polymerization) Using Dithiocarbamates as Chain Transfer Agents, Product Details of C12H17NS2, the publication is Macromolecules (1999), 32(21), 6977-6980, database is CAplus.

Living radical polymerization with reversible addition-fragmentation chain transfer (RAFT polymerization) can be achieved with the use of dithiocarbamate derivatives that have the nonbonded electron pair of the nitrogen included as part of an aromatic system. These compounds have been shown to be highly effective in RAFT polymerization of styrene and (meth)acrylate esters to produce polymers of predetermined mol. weight and narrow polydispersity (usually <1.2). By contrast, simple N,N-dialkyl dithiocarbamates (those compounds previously described as “photoiniferters”) are ineffective as RAFT agents. The reasons for the different behavior are discussed.

Toumi, Meriem published the artcileElectrogenerated base-promoted synthesis of dithiocarbamate acid esters and 3-(N-substituted-amino)-2-cyanodithiocrotonates from primary or secondary amines and carbon disulfide, Quality Control of 3052-61-7, the publication is Phosphorus, Sulfur and Silicon and the Related Elements (2007), 182(10), 2477-2490, database is CAplus.

Dithiocarbamates and 3-amino-2-cyanodithiocrotonates were prepared by condensation of secondary and primary amines with carbon disulfide alkylation reagent and acetonitrile, promoted by electrogenerated acetonitrile anion. Condensation of secondary amines R¹R²NH with CS₂ and R³X in MeCN, promoted by acetonitrile anion electrogeneration, gave dithiocarbamates R¹R²NCS₂R³ (1, R¹, R² = Et, ⁱPr; R¹R²N = 1-pyrazolyl, 1-imidazolyl, 9-carbazolyl, 4-morpholinyl) as the main products, together with 3-amino-2-cyanodithiocrotonates R³S₂CC(CN):C(Me)NH₂, resulting from autocondensation of two acetonitrile mols. followed by addition of CS₂ and alkylation. Primary amines R¹NH₂ gave mainly the 3-amino-2-cyanodithiocrotonates R³S₂C(CN):C(Me)NHR¹ as a result of condensation of amide anion R¹NH^– with two acetonitrile mols., ammonia elimination and condensation with CS₂. The mechanisms are discussed.
