Palladium-Catalyzed Regioselective B(3,5)-Dialkenylation and B(4)-Alkenylation of <i>o</i>-Carboranes.

ABSTRACT: Picolyl group directed B(3,5)-dialkenylation and B(4)-monoalkenylation of o-carboranes has been developed with a very low palladium catalyst loading. The degree of substitution is determined by the cage C(2)-substituents due to steric reasons. On the basis of experimental results, a plausible mechanism is proposed including electrophilic palladation and alkyne insertion followed by protonation.
