A palladium-catalyzed deformylative P-C cross-coupling reactions of hydroxymethylphosphine derivatives enables a practical and versatile syntheses of tertiary phosphine derivatives. Sequential couplings of orthogonally protected precursors provide a simple and practical route toward a variety of tertiary aryl-substituted phosphine derivatives in any combination.

A catalytic amount of a Brønsted base mediates a stereoselective diphosphination of terminal alkynes with diphosphanes to deliver the corresponding (E)-1,2-diphosphinoethenes in good yields. This reaction offers a good alternative to precedented transition-metal-catalyzed or radical-promoted approaches to the 1,2-diphosphinoethene framework of potent interest in catalysis and coordination chemistry.

A stereoselective hydrophosphination reaction of alkynes with diphenylphosphane has been developed. The reaction is mediated by a cobalt catalyst and butyllithium.
