Rh（I）-Catalyzed Reaction of Trifluoromethylketone N-Tosylhydrazones and Arylboronates

Rh（I）-C.atalyzed synthesis of 1,1-difluoro-2,2-diarylalkenes from trifluoromethylketone N-tosylhydrazones and arylboronates is presented in this communication. This new synthetic method is based on the Rh（l）-carbene migra- tory insertion followed by fl-fluoride elimination. In one particular case th...

Summary:Rh（I）-C.atalyzed synthesis of 1,1-difluoro-2,2-diarylalkenes from trifluoromethylketone N-tosylhydrazones and arylboronates is presented in this communication. This new synthetic method is based on the Rh（l）-carbene migra- tory insertion followed by fl-fluoride elimination. In one particular case the protonation occurs instead offl-fluoride elimination, affording 2,2-diaryl trifluoroethane product.
