“…Deprotection of TMS ethers to their corresponding alcohols under mild reaction conditions is of practical importance and several methods and catalysts such as bismuth(III) salts, [23] NaBrO 3 -NH 4 Cl, [24] PhCH 2 PPh 3 HSO 5 , [25] Zr(KPO 4 ) 2 , [26] potassium dodecatungstocobaltate(III) trihydrate, [27] cobalt(II) tetrasulfophthalocyanine, [28] trimethylsilyl bromide, [29] CuBr 2 , [30] tetraethylammonium superoxide, [31] DABCO-bromine, [32] sulfated SnO 2 [33] and LiOAc [34] have been reported for this transformation. However, in some of the reported methods one or more disadvantages, such as harsh reaction conditions, high reaction temperatures, long reaction times, high cost or toxicity of the reagents have been experienced.…”
