The first catalytic double hydrophosphination of alkynes was achieved by reaction with diarylphosphines in the presence of an iron catalyst. The double hydrophosphination proceeded regioselectively and effectively for various secondary arylphosphines and terminalalkynes to give 1,2-bisphosphinoethane derivatives.

A commercially available iron compound, [CpFe(CO)2]2 (1) (Cp = η5-C5H5), is an efficient catalyst for the double hydrophosphination of terminal aryl alkynes with diphenylphosphine under visible light irradiation or thermal conditions with a reduction of reaction times of up to two orders of magnitude for some substrates over literature reports. The 1,2-bis(diphenylphosphino)ethane products generated
市售的铁化合物,[CpFe的量(CO)2 ] 2(1)(CP =η 5 -C 5 H ^ 5),是用于与二苯基膦可见光照射或热的条件下末端芳炔烃组成的双hydrophosphination一个有效的催化剂与文献报道相比,某些底物的反应时间缩短了两个数量级。在这些反应中产生的1,2-双(二苯基膦基)乙烷产物很容易以高收率分离。
