Tris(tert-butoxy)silanethiol is a silicon compound containing three tert-butoxy groups and a rare Si-S-H functional group. This colourless compound serves as an hydrogen donor in radical chain reactions. It is prepared by alcoholysis of silicon disulfide and purified by distillation:
3 (CH3)3COH + SiS2 → [(CH3)3CO]3SiSH + H2SReferences
