title: Aminosilanetrithiol RSi(SH)(3): an experimental and quantum-chemical study.
abstract: An interesting aminosilanetrithiol RSi(SH)3 (R = N(SiMe3)-2,6-iPr2C6H3) has been prepared by the reaction of lithium aminosilanetrithiolate {RSi[SLi(THF)]3}2 with MeCOOH. Theoretical calculations indicate that the LP(N) → σ*(Si-S) and LP(S) → σ*(Si-S) electron donations remarkably contribute to the stabilization of the Si(SH)3 part of the molecule. RSi(SH)3 is the first example of a stable molecule containing three SH groups attached to one element.
