A new method for removal of trialkylsilyl groups from silyl ethers using Complex A and Complex B, generated from tetrabutylammonium fluoride (TBAF) and BF3·Et2O has been developed. The desilylation by use of these boron complexes is significantly affected by the steric factor on the Si atom and the reagent.
开发了一种新的方法,该方法使用由氟化四丁基铵(TBAF)和BF 3 ·Et 2 O生成的络合物A和络合物B从甲硅烷基醚中除去三烷基甲硅烷基。通过使用这些硼配合物的去甲硅烷基化作用显着地受到Si原子和试剂上的空间因素的影响。
