  High Atom-Economical One-Pot Synthesis of Secondary Phosphines and Their Borane Complexes Using Recycling Phosphorus Donor Reagent

  摘要：

  A general new method for the one-pot preparation of secondary phosphines 11 and in situ generation of their borane complexes 12 is described. This method consists of the sequential addition, at room temperature, of equivalent amounts of (RMgBr)-Mg-1 and (RMgBr)-Mg-2 to 1 equiv of the phosphorus atom donor reagent 1. Final treatment with water gives secondary phosphines (RRPH)-R-1-P-2 (or the corresponding phosphine-borane complexes if treated with BH3-THF) and the end product 6, which can be recycled.

  to be outstanding reductants for secondary phosphine oxides (SPOs). All classes of SPOs can be readily reduced, including diaryl, arylalkyl, and dialkyl members. Many SPOs can now be reduced at cryogenic temperatures, and conditions for preservation of reducible functional groups have been found. Even the most electron-rich and sterically hindered phosphine oxides can be reduced in a few hours at 50-70
