THIOLS, UNSYMMETRICAL SULFIDES AND THIOACETALS FROM THE NEW REAGENT: TRIISOPROPYLSILANETHIOL
Triisopropylsilanethiol (HSTIPS, 1), easily prepared in 98percent yield from H2S and TIPSCl, is efficiently alkylated in a selective manner with 10 and 20 alkyl halides or tosylates through its potassium thiolate (2c) to provide RSTIPS (3) in excellent yields.Compound 3 provides a convenient source of alkanethiols (4), unsymmetrical dialkyl sulfides (5) and thioacetals (6).
