Simple unprecedented conversion of phosphine oxides and sulfides to phosphine boranes using sodium borohydride

Rajendran, Kamalraj V.,Gilheany, Declan G.

supporting information; body text, p. 817 - 819 (2012/02/03)

A variety of phosphine oxides and sulfides can be efficiently converted directly to the corresponding phosphine boranes using oxalyl chloride followed by sodium borohydride. Optically active P-stereogenic phosphine oxides can be converted stereospecifically to phosphine boranes with inversion of configuration by treatment with Meerwein's salt followed by sodium borohydride.
