Terminal phosphanido rhodium complexes mediating catalytic P-P and P-C bond formation

Complexes with terminal phosphanido (MPR2) functionalities are believed to be crucial intermediates in new catalytic processes involving the formation of PP and PC bonds.

Descripción
Sumario:Complexes with terminal phosphanido (MPR2) functionalities are believed to be crucial intermediates in new catalytic processes involving the formation of PP and PC bonds. We showcase here the isolation and characterization of mononuclear phosphanide rhodium complexes ([RhTp(H)(PR2)L]) that result from the oxidative addition of secondary phosphanes, a reaction that was also explored computationally. These compounds are active catalysts for the dehydrocoupling of PHPh2 to Ph2PPPh2. The hydrophosphination of dimethyl maleate and the unactivated olefin ethylene is also reported. Reliable evidence for the prominent role of mononuclear phosphanido rhodium species in these reactions is also provided.
