An efficient procedure has been developed for the alkylation of cyclic ketones, based on the reaction of trialkylboranes with cyclic α-diazo ketones. The reaction proceeds under mild conditions, affords high yields of α-alkylated cycloalkanones, and circumvents certain difficulties inherent in previous alkylation methods.

A palladium-catalyzed oxidative cross-coupling of vinyl boronic acids and cyclic α-diazocarbonyl compounds has been reported. The reaction constitutes an efficient method for the synthesis of 1,3-diene compounds bearing a ring structure. Mechanistically, the reaction involves migratory insertion of palladium carbene as the key step.
