This study describes Si-Si bond cleavage of perchlorooligosilane using an amine. N-Methylaniline-induced Si-Si bond cleavage reactions of cyclic perchlorosilanes Si5Cl10 (1) and Si4Cl 8 (2), and acyclic perchlorosilanes Si5Cl12 (3) and Si2Cl6 (4) yielded the N,N-methylphenylamino- substituted monosilanes, (NMePh)3-nSiHCln (5; n = 2, 6; n = 1, 7; n = 0) and (NMePh)4-nSiCln (8; n = 2, 9; n = 3). Products and yields depended on the perchlorooligosilanes used. In addition, disproportionation between Si-N and Si-Cl bonds was observed in reactions of compounds 5 and 9.
