摘要

The Pd-catalyzed carbonylation of ω-vinyl-substituted o-iodoalkenylbenzenes 1-4 can provide up to modest yields (50-60%) of 5-and 6-membered Type I cyclic acylpalladation products, ie, α, β-unsaturated cyclic ketones, in the absence of an external nucleophile and high yields of 5-and 6-membered Type II cyclic acylpalladation products, ie, α-or β- ((alkoxycarbonyl) methyl) substituted cyclic ketones in the presence of an alcohol, eg, ...
