Copper(I)-catalyzed hydrophosphination of styrenes
摘要:
Hydrophosphination of styrenes has been accomplished with metal salts for the first time. (CuOTf)(2).toluene complex is the catalyst of choice, but CuCl can also be used. "In-situ" EPR and NMR studies suggest Cu(I) as the catalytically active metal species, giving exclusively the anti-Markovnikov product. Phosphine oxides or beta-ketophosphine oxides can be prepared in one-pot by oxidation with molecular oxygen. (C) 2010 Elsevier B.V. All rights reserved.
