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 was first prepared by alcoholysis of silicon disulfide and purified by distillation:[1]
Since 1962 it was thoroughly studied including its acid-base properties[2][3] and coordination chemistry with metal ions. It coordinates to metal ions via the sulfur and oxygen donor atoms.[4][5][6][7][8][9]
