proximal SH or NH activating groups located at the α- or β-position to the P=O bond. A generalized reduction mechanism has been proposed. Tertiary sulfanylphosphine and aminoalkylphosphine oxides can be easily converted into the corresponding tertiary sulfanylphosphine- and aminoalkylphosphine-boranes, respectively, through the facile P=O bond reduction by borane complexes. The easy reduction of the
摘要 叔硫烷基膦和氨基烷基膦氧化物可以很容易地通过硼烷络合物容易的P = O键还原分别转化为相应的叔硫烷基膦-和氨基烷基膦-硼烷。通过轻度还原剂BH 3可以轻松还原强P = O键,这是通过位于α-或β-位的近端SH或NH活化基团指导分子内P = O-B络合而实现的。 P = O键。已经提出了一种广义的归约机制。 叔硫烷基膦和氨基烷基膦氧化物可以很容易地通过硼烷络合物容易的P = O键还原分别转化为相应的叔硫烷基膦-和氨基烷基膦-硼烷。通过轻度还原剂BH 3可以轻松还原强P = O键,这是通过位于α-或β-位的近端SH或NH活化基团指导分子内P = O-B络合而实现的。 P = O键。已经提出了一种广义的归约机制。
