Novel organylthio(alkoxy)silanes (I, II, III and XII) and organylthio(diethylamino)silanes (IV, V) are described. They were prepared by treating lithium or lead thiolates with the corresponding chlorosilanes or by cleavage of dimethylbis(diethylamino)silane with thiols. Phenylthiosilanes (Me3SiSPh, III and XIII) furthermore can be obtained by reaction of chlorosilanes with benzenethiol in the presence
The differing modes of reaction of 1-(8-dimethylamino-1-naphthyl)-1-hydrodisilane and 1-(1-naphthyl)-1-hydrodisilane in nickel-catalyzed reactions with acetylene: formation of a pseudo-pentacoordinate silole via SiSi bond cleavage vs. hydrosilation without SiSi bond cleavage

Pseudo-pentacoordinate 1-(8-dimethylamino-1-naphthyl)-1-hydrodisilanes 1 and 2 and the tetracoordinate counterpart 3 have been prepared. In the presence of an Ni(0) complex as catalyst, 1 and 2 undergo degradation to generate a silylene species and a hydrosilane. The complex with Ni of the silylene species from 1 has been trapped with an excess of diphenylacetylene to give a pseudo-pentacoordinate

The treatment of several branched methylchlorooligosilanes (Si-4, Si-5) with diethylamine leads to a partial or complete substitution of the chloro substituents for diethylamino groups under formation of the first known (diethylamino)-methylchlorooligosilanes containing more than two Si atoms. The condensation of (Et2N)(2)MeSi-SiMeCl(NEt2) (1d) with Li in THF yields the linear tetrasilane (Et2N)(2)MeSi-SiMe(NEt2)-SiMe(NEt2)-SiMe(Et2N)(2) (2a).The NMR investigations provided information of the general shift ranges of several Si units in (diethylamino)-methylchlorooligosilane systems as well as the number of stereoisomers of the prepared products.
