The Pd-catalyzed carbonylative cyclization reaction involving ω-acyl-substituted acylpalladium derivatives can proceed via intramolecular trapping with either C- or O-enolates; the preferential formation of either 5- or 6-membered rings dictates the C-to-

Treatment of o-iodoaryl alkenyl ketones with CO (600 psi) in CH3CN in the presence of 5 mol percent of Pd(dba)2 and 1 equiv of NEt3 can give bicyclic and polycyclic quinones in high yields via acylpalladation in an "endo" mode, which appears to be totally
