Regioselective functionalization of nonactivated CH bonds. 2. Photochemical functionalization of the myristoyl group in 1,2-alkanediyl and o-phenylene 4-benzoylbenzoate myristates was written by Dors, Bernhard;Luftmann, Heinrich;Schaefer, Hans J.. And the article was included in Chemische Berichte in 1983.Recommanded Product: 3903-40-0 This article mentions the following:
Me(CH2)12CO2QO2CC6H4COPh-4 (Q = CH2CH2, trans-1,2-cyclohexanediyl, o-phenylene) were prepared and cyclized photochem. to I, which were converted to Me 7- to 13-oxomyristates. This ketofunctionalization of the remote CH2 groups in myristic acid was more selective than in 4-PhCOC6H4CO2(CH2)nMe (n = 11, 15, 16, 17), and the maximum functionalization occurred more toward the middle, rather than the end, of the chain. The solvent polarity had only a small effect on the selectivity. In the experiment, the researchers used many compounds, for example, 12-Methoxy-12-oxododecanoic acid (cas: 3903-40-0Recommanded Product: 3903-40-0).
12-Methoxy-12-oxododecanoic acid (cas: 3903-40-0) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Esters contain a carbonyl center, which gives rise to 120掳 C鈥揅鈥揙 and O鈥揅鈥揙 angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C鈥揙鈥揅 bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
