Palladium-catalyzed disilylation of o-quinodimethanes: synthesis of 9- and 10-membered disilacarbocycles.
o-Quinodimethanes are efficiently inserted into a silicon-silicon bond of cyclic disilanes in the presence of a palladium-diphenyl-2-pyridylphosphine catalyst, giving 9- and 10-membered disilacarbocycles, that is, benzodisilonine and benzodisilecine.
