A NOVEL SYNTHESIS OF 1,2-DIARYL-2,2-DIFLUOROETHANONES
Yu, Kuo-Long,Mansuri, Muzammil M.,Starrett, John E.
, p. 8955 - 8956 (1994)
A novel procedure for the synthesis of 1,2-diaryl-2,2-difluoroethanones involving Stille reaction of an aryl difluoroacetyl chloride and an arylstannane has been developed.Application of this procedure for the preparation of two retinoids is described.
