Perchloropolysilane: X-Ray Structure, Solid-State29Si NMR Spectroscopy, and Reactions of [SiCl2]n
摘要:
The silicon backbone is all-trans in the crystal structure of perchloropolysilane [SiCl2 ]n (see structure on the right). The Cl atoms can be substituted by nucleophiles to form polymers such as peralkoxy- and peraminopolysilanes.
N-Methylaniline-induced Si–Si bond cleavages of perchlorooligosilanes
摘要:
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 Si4Cl8 (2), and acyclic perchlorosilanes Si5Cl12 (3) and Si2Cl6 (4) yielded the N,N-methylphenylamino-substituted monosilanes, (NMePh)(3-n)SiHCln (5; n = 2, 6; n = 1, 7; n = 0) and (NMePh)(4-n)SiCln (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. (C) 2014 Elsevier B.V.
