Nickel-catalyzed reactions of 3,4-benzo-1,1,2,2-tetraethyl-1,2-disilacyclobutene
摘要:
The reaction of 3,4-benzo-1,1,2,2-tetraethyl-1,2-disilacyclobutene (1) with benzene in the presence of a catalytic amount of Ni(PEt3)4 afforded 1-diethylphenylsilyl-2-(diethylsilyl)benzene, while reaction with diphenylacetylene and benzaldehyde gave the respective products arising from insertion of 1 into an Si-Si bond.
