The hydrophosphination of carbon-carbon multiple bonds has been generally performed under acid, base or metal catalysis in different solvents. Herein, alkyl and alkenyl tertiary phosphines are obtained by the addition...
An Ir(ppy)3-catalyzed vic-diphosphination of styrenes with Me3Si-PPh2 and NFSI proceeds under blue LED irradiation to afford the corresponding bis(diphenylphosphino)ethane derivatives without any formation of hydrophosphination byproducts, which are inevitable and problematic under the previous Cu/NHC catalysis. Additionally, the visible-light-promoted photoredox catalysis enables the diphosphination
Me 3 Si-PPh 2和NFSI对苯乙烯进行Ir(ppy)3催化的维克二磷酸化,在蓝色LED辐射下进行,得到相应的双(二苯基膦基)乙烷衍生物,而没有形成任何磷酸化副产物,这在不可避免的情况下是有问题的先前的Cu / NHC催化。另外,可见光促进的光氧化还原催化能够使相对具有挑战性的脂族烯烃和β-取代的苯乙烯进行二磷酸化。

A copper/N‐heterocyclic carbene (NHC) catalyzed oxidative vicinal diphosphination of styrenes with diphenyl(trimethylsilyl)phosphine proceeds in the presence of LiOtBu and a pyridine N‐oxide/MnO2 combined oxidant to deliver the corresponding 1,2‐bis(diphenylphosphino)ethanes (DPPEs) in good yields. The present copper catalysis can provide access to the DPPE‐type ligands directly from the relatively

allylphosphanes has been developed using nBuLi-mediatedhydrophosphination of conjugated dienes. In all the cases the phosphorus atom of the reacting phosphane attacked the sterically less demanding side of the diene exclusively. In addition, high regioselectivities towards 1,2- or 1,4-addition products were observed depending on the nature of the dienes. This hydrophosphination reaction was extended to a variety
