Fluorinated β-diketo phosphorus ylides: Their cyclocondensation with amidines affording 4-trifluoromethyl- And 4-perfluoroalkyl-substituted pyrimidines

A study is presented for the syntheses of a series of 4-trifluoromethyl- and 4-perfluoroalkyl-substituted pyrimidines from the reaction of trifluoromethyl or perfluoroalkyl β-diketo phosphorus ylides (Ph3P=C(CORF)COR) with amidine hydrochloride.
