Palladium-Catalyzed Complete Regio- and Stereoselective Vicinal trans-Bisphosphination of Terminal Alkynes with Air- and Moisture-Stable Diphosphine Disulfides.

A palladium-catalyzed completely regio- and stereoselective vicinal trans-bisphosphination of terminal alkynes has been achieved using air- and moisture-stable tetraphenyldiphosphine disulfide as the phosphorus source. The developed system shows outs…
