6-membered Type I cyclic acylpalladation products, i.e., α,β-unsaturated cyclicketones, in the absence of an external nucleophile and high yields of 5- and 6-membered Type IIcyclic acylpalladation products, i.e., α- or β-((alkoxycarbonyl)methyl)substituted cyclicketones in the presence of an alcohol, e.g., MeOH. In cases where no such processes are available, other side reactions, such as cyclic carbopalladation
