Triisopropylsilanethiol (HSTIPS, 1), easily prepared in 98% yield from H2S and TIPSCl, is efficiently alkylated in a selective manner with 1° and 2° 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).
三异丙基硅烷硫醇(HSTIPS,1)易于从H 2 S和TIPSCl中以98%的收率制备,并通过1°和2°烷基卤化物或甲苯磺酸盐通过其硫醇钾(2c)有效地烷基化以提供RSTIPS(3)高产。化合物3提供了链烷硫醇(4),不对称二烷基硫化物(5)和硫缩醛(6)的方便来源。
