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.
