Activation of carbon disulfide by a hypersilyl germylene

In this work, the insertion of CS 2 into the Ge-Si bond of PhC(N t Bu) 2 Ge-Si(SiMe 3 ) 3 ( 1 ) has been investigated, resulting in the formation of PhC(N t Bu) 2 Ge-C(&z.dbd;S)-S-Si(SiMe 3 ) 3 ( 2 ). Interestingly, the addition of NHC to 2 allows the release of NHC·CS 2 with concomitant regeneration of 1 . Addition of another equivalent of 1 or an analogous hypersilyl silylene, [PhC(N t Bu) 2 Si-Si(SiMe 3 ) 3 ], to 2 led to the formation of compounds with a Ge&z.dbd;S ( 3 ) or a Si&z.dbd;S ( 4 ) bond. In this work, the insertion of CS 2 into the Ge-Si bond of PhC(N t Bu) 2 Ge-Si(SiMe 3 ) 3 ( 1 ) has been investigated, resulting in the formation of PhC(N t Bu) 2 Ge-C(&z.dbd;S)-S-Si(SiMe 3 ) 3 ( 2 ).
