Photochemical behaviors of tetraphenyldiphosphine in the presence of alkynes

Under an atmosphere of nitrogen, the photoinduced reaction of tetraphenyldiphosphine (1) with alkynes (2) generates vicinal bisphosphinated alkenes (3) as air-sensitive compounds, which can be isolated by treatment with elemental sulfur. A novel E to Z isomerization of 3 is revealed to take place upon continuous photoirradiation.

Br?nsted Base Mediated Stereoselective Diphosphination of Terminal Alkynes with Diphosphanes

A Br?nsted base mediated stereoselective diphosphination of terminal alkynes with diphosphanes proceeds to deliver the corresponding (E)-1,2-diphosphinoethenes in good yields. The reaction of aromatic alkynes occurs efficiently in the presence of a catalytic amount of LiO-t-Bu while MN(TMS)2 (M = Li or Na) gave better results in the case of aliphatic substrates. The Br?nsted base mediated protocol can offer 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.

Copper-catalyzed anti-hydrophosphination reaction of 1-alkynylphosphines with diphenylphosphine providing (Z)-1,2-diphosphino-1-alkenes

Hydrophosphination of 1-alkynylphosphines with diphenylphosphine proceeds in an anti fashion under copper catalysis, providing an easy and efficient access to a variety of (Z)-1,2-diphosphino-1-alkenes and their sulfides. The reaction is highly chemoselec
