A novel intramolecular Wittig reaction, via ylide-anion formation and protonation and its application to the synthesis of perfluoroalkylated α,β-unsaturated carbonylcompounds are described.
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 trifiuoromethyl or perfluoroalkyl beta-diketo phosphorus ylides (Ph3P=C(CORF)COR) with amidine hydrochloride.
