The triorganyl-phosphane/-phosphite-Ni(O) catalyzed cycloaddition of methylenecyclopropane (1) with electron deficient alkenes leads regioselectively to 2,3- or 3,4-disubstituted methylenecyclopentanes depending on the electronic properties of the ol
Reactions of Methylenecyclopropanes, V. Palladium(0)-catalyzed Codimerisation of Methylenecylopropane with Methyl Acrylates and 1,2-Ethylenedicarbonic Esters

Triorganylphosphane-modified palladium(0) compounds catalyze the codimerisation of methylenecyclopropane (1) with methyl acrylate, methyl trans-crotonate or trans-cinnamate to give the methylenecyclopentanecarboxylic esters 3, 4, 5; diethyl fumarate or dimethyl maleate and 1 lead to the methylenecyclopentanedicarbonic esters 12.With diethyl maleate besides cis/trans-12b also oligomers containing two mols of 1 and one (cis/trans-14) or two mols of the diester (cis/trans-15) are formed.
