Abstract
| - We report that a combination of DPPF(1,1-bis(diphenylphosphino)ferrocene) andPd(dba)2 leadsto the amination of aryl triflates, a reaction that allows for theconversion of phenols to arylamines.A combination of BINAP and Pd(dba)2 alsocatalyzes the amination of aryl triflates, butP(o-tolyl)3complexes were not effective catalysts. In some cases, slowaddition of the aryl triflate was necessaryto prevent cleavage of the triflate and generation of phenol. Wefound that added halide, necessaryin some cross-coupling chemistry of aryl sulfonates, was an unnecessaryadditive and even inhibitedthe amination chemistry.
