Method of producing dicarboxylic acids
-
Page/Page column 13; 19, (2009/05/29)
A method of producing dicarboxylic acids (e.g., α,ω dicarboxylic acids) by reacting a compound having a terminal COOH (e.g., unsaturated fatty acid such as oleic acid) and containing at least one carbon-carbon double bond with a second generation Grubbs catalyst in the absence of solvent to produce dicarboxylic acids. The method is conducted in an inert atmosphere (e.g., argon, nitrogen). The process also works well with mixed unsaturated fatty acids obtained from soybean, rapeseed, tall, and linseed oils.

Cometathesis of methyl oleate with 1-hexene or with other α-olefins affords two new esters and two new olefins.In the case of 1-hexene these products are methyl 9-decenoate, methyl 9-tetradecenoate, 1-decene and 5-tetradecene.At the same time, the formation of the esters and olefins with shorter chains (i.e. decene and decenoate) is distinctly preferred.Obviously, the transfer of methylene group from the alkene to the ester molecule is much easier than that of the alkylidene moiety.The non-stoichiometric course of cometathesis is associated with the carbene mechanism of the reaction.
