摘要

Recently, tetra??butyl ammonium tribromide (TBATB), TiCl 4 –Lewis base complexes, and NaHSO 4 on silica have also been reported for the deprotection of TBDMS ethers.6 View all references However, most of these methods require hazardous reagents and cumbersome workup procedures that are detrimental to the environment. Moreover, in nearly all cases, the reagent cannot be recovered and recycled except for NaHSO 4 on silica, for which catalyst??to??substrate ...
