SYNTHESIS OF 2,2,2-TRISUBSTITUTED 5-TRIFLUOROMETHYL-Δ4-1,3,4,2-OXADIAZAPHOSPHOLINES AND THEIR POTENTIALITY AS PRECURSORS OF TRIFLUOROACETONITRILE IMINES

N'-Phenyl- and methyltrifluoroacetohydrazides react with phosphorus pentachloride to give the corresponding 2,2,2-trichloro-3-phenyl- and methyl-Δ4-1,3,4,2-oxadiazaphospholines, from which various 2,2,2-trisubstituted derivatives are further synthesized.Heating 3-phenyl-2,2,2-tris(p-tolyloxy) analog with an excess of styrene affords 1,5-diphenyl-3-trifluoromethyl-2-pyrazoline, which indicates that the phospholine behaves as a precursor of trifluoroacetonitrile phenylimine.
