Alkylation of Hydrochlorosilanes

“…Of compounds with the structure (SiX,)?R where X is halogen, only those where R represents methylene (11,18), dimethylene (3,11), and trimethylene (3) have been described, while no compound of the type (SiH3)2R has been reported.…”

By passing appropriate dichloroalkanes, e.g. 1,l-dichloroethane, over a mixture of silicon and copper a t elevated temperatt~re, the new c o m p o~~n d s l,l-bistrichlorosilylethane, 1,2-bis-trichlorosilylpropa~~e, and 1,4-bis-trichlorosilylbutane and the previously reported bis-trichlorosilylnietharie, dichlorosilyltriclilorosilylmethane, a~~d 1,2-bis-trichlorosil ylethane were synthesized. Trichloromethane yielded perchlorodisilane; 2-chloropropane gave propene.By causi~tg the chlorosilylalkanes to react with lithium aluminum hydride, disilylmethane, 1,l-disilylethane, l,2-disilyletliane, and l,2-disilylpropane were synthesized..Several physical constants of the conipour~ds were measured.

“…After the work described in this report had been completed very recent work (15) on the addition of trichlorosilane to trimethylvinylsilane as well as to other vinylsilanes came to our attention. It has been reported (13) that methyldichlorosilane does not add to olefins as readily as does trichlorosilane. However, in the present study it was found that addition of methyldichlorosilane to trimethylvinylsilane gives yields com- parable to those obtained by addition of trichlorosilane if the reaction mixture is refluxed for an extended time.…”

“…While many examples of the addition of silanes containing Si-H links to olefins have been published since this reaction was first reported (12), little work has been reported on such additions to alkanylsilanes. Trichlorosilane has been added to vinyl-and allyl-trichlorosilane (13) and to trimethylallylsilane (14) to give 1,2-bis-(trichlorosilyl)ethane, 1,3-bis-(trichlorosilyl)propane, and a-trimethylsilylpropyltrichlorosilane respectively. After the work described in this report had been completed very recent work (15) on the addition of trichlorosilane to trimethylvinylsilane as well as to other vinylsilanes came to our attention.…”
