The electroreduction of organo-substituted dichlorosilanes, Me2SiCl2, MeEtSiCl2, MePrSiCl2, MeHexSiCl2, Me(c-Hex)SiCl2, MePhSiCl2, and Ph2SiCl2 in THF, is reported. A 2-step reduction scheme (E1: RR’SiCl2 ⇌ [RR’SiCl2]•- and E2: [RR’SiCl2]•- ⇌ [RR’SiCl2]2-) is suggested in which the redox potentials E1 and E2 are separated by ∼110 mV. A simulation of the irreversible voltammograms indicates multiple pathways in producing silyl anion, among them the decomposition of dianion and/or the disproportionation of silyl anion radicals, which is further corroborated by low-temperature cyclic voltammetric measurements. Subsequently, silyl anion undergoes SN2 nucleophilic attack on another chlorosilane mol. to form Si-Si bonds. Taft substituent constants were applied and proved effective in correlating the substituent effect on the reduction of dichlorosilanes. For dialkyl-substituted chlorosilanes, the Taft anal. of the polar contribution of substituents to the cathodic peak shift gives a pos. ρ*∼2.4, which indicates an SN2 nucleophilic reaction in the formation of silyl dianion intermediate. The steric effect of substituents, however, is largely responsible for the stability of the SN2 transition state.
