Mixed dialkylaluminum chlorides and mixed trimethylorganoaluminates in chemoselective 1,4-addition reactions to alkylidene malonic acid diethyl ester was written by Maas, Steffen;Kunz, Horst. And the article was included in Journal fuer Praktische Chemie (Weinheim, Germany) in 2000.Application of 10203-58-4 This article mentions the following:
Mixed (alkyl)methylaluminum chlorides (aryl)methylaluminum chlorides were formed by reaction of methylaluminum dichloride with organolithium or Grignard compounds and used for chemoselective 1,4-addition of higher alkyl, aryl, alkenyl and alkynyl groups to (alkylidene)propanedioates. Such aluminum reagents were prepared in situ; for example: (butyl)methylaluminum chloride, lithium butyltrimethylaluminate(1-), chloro(1-hexynyl)methylaluminum, chloro(ethenyl)methylaluminum. As an alternative, mixed trimethylorganoaluminates can also be applied for these Michael addition reactions. For conjugate addition of alkenyl groups to (alkylidene)propanedioates, alkenyl diisopropylalanes obtained from alkynes and diisopropylaluminum hydride proved the most efficient reagents. Using these novel mixed organoaluminum compounds, 灏?branched malonic (carboxylic) acid derivatives were obtained in good yields. The method offers a general access to 灏?branched carboxylic derivatives of quite diverse structure not dependent on the com. availability of the organoaluminum chlorides. In the experiment, the researchers used many compounds, for example, Diethyl isobutylmalonate (cas: 10203-58-4Application of 10203-58-4).
Diethyl isobutylmalonate (cas: 10203-58-4) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Application of 10203-58-4
