Process for the preparation of unsaturated alpha, omega dicarboxylic acid diesters

摘要

Preparation of unsaturated alpha, omega dicarboxylic acid diesters, comprises converting unsaturated fatty acids and/or unsaturated fatty acid esters in the presence of catalyst comprising dichloro-[1,3- bis(mesityl)-2-imidazolidinylidene]-(3-phenyl-1H-inden-1-ylidene)(tricyclohexylphosphine)ruthenium (II) and/or [1,3-bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene]-[2-[[(4-methylphenyl)imino]methyl]-4-nitrophenolyl]-[3-phenyl-1H-inden-1-ylidene]ruthenium(II) chloride.
