Use of the more reactive tetrabromosilane leads to the bis- and tris-(chloro-methyl) compounds without the necessity for a catalyst.383 Diazomethane reacts with trichlorosilane or trichloro(methyl)silane in the presence of copper powder to yield, respectively, dichloro(chloromethyl)silane385 386 and di-chloro(chloromethyl)(methyl)silane,383 but no chloromethyl derivative can be obtained in this way from chlorosilanes carrying three organic groups, such as chloro-(trimethyl), -(triethyl)-, and -(triphenyl)-silane.

A new type of asymmetric hydrosilylation which produces axially chiral allenylsilanes has been reported by use of a palladium catalyst coordinated with the bisPPFOMe ligand 51b.64 The hydrosilylation of l-buten-3-ynes substituted with bulky groups such as tert-butyl at the acetylene terminus took place in a 1,4-fashion to give allenyl(trichloro)-silanes with high selectivity. The highest enantioselectivity (90% ee) was observed in the reaction of 5,5-dimethyl-T hexen-3-yne with trichlorosilane catalyzed by the bisPPFOMe-palladium complex (Scheme 13).

The technique for producing vinyltrichlorosilane by attaching trichloro-silane to acetylene in the presence of a catalyst can be promising, but the conditions of this reaction have not been studied well enough. The most acceptable technique for obtaining vinyltrichlorosilane by high-temperature condensation (HTC) of trichlorosilane with vinylchloride is ...

Silanes are widely recognized as efficient reagents for reduction of carbonyl and heterocarbonyl functionality. In the case of alkyl and arylsilanes, the reaction requires catalysis by Lewis acids or transition metal complexes 1, 3] however, with more Lewis acidic trichloro or trialkoxysilanes, an altemative metal free activation can be accomplished. Thus, it has been demonstrated that extracoordinate silicon hydrides, formed by the coordination of silanes to Lewis bases, such as tertiary amines 7a], DMF [7b] or MeCN, and so on [7], can serve as mild reagents for the reduction of imines to amines [8]. In the case of trichlorosilane, an inexpensive and relatively easy to handle reducing reagent, and DMF as a Lewis basic promoter, the intermediacy of hexacoordinate species has been confirmed by Si NMR spectro scopy [7b].

In 1993 Uozumi et al. reported on the regio- and enantioselective hydrosilylation of styrene derivatives using an optically active palladium catalyst [1]. In the context of these examinations the authors also mentioned the reaction of indene with trichlorosilane in all cases the 1-substituted products only were got no further characterization was given, however. In accordance with these results, our investigations on the hydrosilylation of indene with trichlorosilane, chlorodimethyl-silane, and dichloromethylsilane in the presence of Speier s catalyst showed the same addition tendencies by distillation we isolated in high yields trichloro(l-indanyl)silane (la), dichloro(l-in-danyl)methylsilane (lb), and chloro(l-indanyl)dimethylsilane (Ic), respectively (Scheme 1). 

Cycloalkenes can be used, but their reactivity is substantially lower than that of 1-alkenes. Their hydrosilylation proceeds via intermolecular hydrogen or methyl group transfer and depends on the nature of the silane, for example, addition of trichlorosilane to methylcyclohexene in the presence of H2PtCl6 gives trichloro(cyclohexylmethyl)silane as a main product. The hydrosilylation of 1- and 4- er -butylcyclohexene and 1-methyl-1-isopropenylcyclohexane with trichlorosilane proceeds according to a mechanism that requires the migration of a methyl group (see Scheme 21) (147). 

Hydrometalation. The hydrosilylation of alkenes, 1,3-dienes, and 1,4-diene may be realized by Pd(PhCN)2Cl2 with PPhs as the ligand (eqs 118-122). For terminal alkenes, only 2-alkylsilanes were afforded (eq 118). For 2-methyl or 2,3-dimethyl buta-1,3-dienes, a mixture of 1,2- or 1,4-addition products were formed (eq 119). For 2-substituted or 1,2-disubstituted buta-1,3-dienes, 1,4-additon products were generated highly selectively (eq 120). The reaction of cyclopentadiene with HSiCls afforded 2-cyclopentyl trichlorosilane (eq 121), while those of eye lohexa-1,3-diene or cyclohexa-1,4-diene afforded a mixture of trichloro(cyclohex-2-enyl)silane and trichloro(cyclohex-3-enyl)silane (eq 122).
