✦ Synopsis


S~~~WZY: A high regioselectivity has been observed in the palladia catalyzed allylation of "soft" nucleophiles (pentane-2,4-dione and 4-hydroxy-6methyl-2pyrone) when both allylic termini have the same steric requirements and different electronic features.

The palladium catalyzed allylation of proton active substrates is a powerful method of carbon-carbon bond formation. ls2 A conanon mechanistic feature for nucleophiles

A novel palladium-catalyzed three-component polycondensation of 1,2,10,11dodecatetraene, 4,4 -diiodobiphenyl, and nucleophiles was carried out using various carbanions and amines as a nucleophilic part. The polymerization with various sodium diethyl malonates produced polymers in high yields. Partic
