A mild and efficient CsOH-promoted synthesis of ditertiary phosphines
Honaker, Matthew T.,Salvatore, Ralph Nicholas
, p. 277 - 283 (2004)
A mild and efficient method for the synthesis of ditertiary phosphines has been developed. In the presence of cesium hydroxide, molecular sieves, and DMF, various dihalides were coupled with diphenylphosphine at room temperature, and the results have demonstrated that this methodology offers a general synthetic procedure producing a variety of ditertiary phosphines in high yields.
The Trityl-Cation Mediated Phosphine Oxides Reduction

Reduction of phosphine oxides into the corresponding phosphines using PhSiH3 as a reducing agent and Ph3C+[B(C6F5)4]? as an initiator is described. The process is highly efficient, reducing a broad range of secondary and tertiary alkyl and arylphosphines, bearing various functional groups in generally good yields. The reaction is believed to proceed through the generation of a silyl cation, which reaction with the phosphine oxide provides a phosphonium salt, further reduced by the silane to afford the desired phosphine along with siloxanes. (Figure presented.).
Preparation technology of bis(dibenzyl)phosphorane
-
Paragraph 0015, (2019/08/06)
The invention provides a preparation technology of bis(dibenzyl)phosphorane and belongs to the technical field of synthesis of organic matters. The technology comprises the following steps: taking metallic lithium, triphenylphosphine and water to react to generate dibenzylphosphorane; taking the dibenzylphosphorane to react with dihalogenohydrocarbon to generate the bis(dibenzyl)phosphorane. According to a production technology, an intermediate product and an intermediate byproduct do not need to be separated; the technology is simple in technological operation, low in raw material cost and high in yield and can be used for producing the low-cost and high-quality bis(dibenzyl)phosphorane.
