摘要: We report that a combination of DPPF (1,1-bis(diphenylphosphino)ferrocene) and Pd(dba)2 leads to the amination aryl triflates, reaction allows for conversion phenols arylamines. A BINAP also catalyzes but P(o-tolyl)3 complexes were not effective catalysts. In some cases, slow addition triflate was necessary prevent cleavage generation phenol. found added halide, in cross-coupling chemistry sulfonates, an unnecessary additive even inhibited chemistry.
