Tris(''tert''-butoxy)silanethiol is a silicon compound containing three ''tert''-butoxy groups and a rare Si–S–H

functional group In organic chemistry, a functional group is a substituent or moiety in a molecule that causes the molecule's characteristic chemical reactions. The same functional group will undergo the same or similar chemical reactions regardless of the res ...

. This colourless compound serves as an hydrogen donor in radical chain reactions. It was first prepared by alcoholysis of

silicon disulfide Silicon disulfide is the inorganic compound with the formula Si S2. Like silicon dioxide, this material is polymeric, but it adopts a 1-dimensional structure quite different from the usual forms of SiO2. Synthesis, structure, and properties Th ...

and purified by distillation: :3 (CH₃)₃COH + SiS₂ → CH₃)₃COsub>3SiSH + H₂S Since 1962 it was thoroughly studied including its acid-base properties and coordination chemistry with metal ions. It coordinates to metal ions via the sulfur and oxygen donor atoms.A. Pladzyk, A. Ozarowski, Ł.
