Palladium-Catalyzed Disilylation of o-Quinodimethanes: Synthesis of 9- and 10-Membered Disilacarbocycles.

[摘要]：O-Quinodimethanes are efficiently inserted into a Si-Si bond of cyclic disilanes (e.g. 1,1,2,2-tetramethyl-1,2-disilacyclopentane) in the presence of a Pd-diphenyl-2-pyridylphosphine catalyst, giving 9- and 10-membered disilacarbocycles, i.e., benzodisilonine and benzodisilecine, e.g. 54 % 2,2,6,6-tetramethyl-8-phenyl-2,3,4,5,6,7-hexahydro-1H-benzo[g][1,5]disi lonine from Ph [3-phenyl-2-(trimethylsilyl)phenyl]methyl carbonate (o-quinodimethane precursor).
