Reactions of α,β-unsaturated ketones containing a trifluoromethyl group with hydrazine and alkyl-, aryl-, and dialkylhydrazines yield trifluoromethyl-substituted pyrazolidines and pyrazolines.Steric strains in the pyrazolidines facilitate their dehydratio
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.
PREPARATION OF TRIFLUOROACETONITRILE PHENYLAMINE AND ITS REACTIONS WITH SOME DIPOLAROPHILES
Tanaka, Kiyoshi,Maeno, Seiji,Mitsuhashi, Keiryo
, p. 543 - 546 (2007/10/02)
Trifluoroaceto-N-phenylhydrazonoyl halides, the precursors of trifluoroacetonitrile phenylamine, prepared by halogenation of trifluoroacetaldehyde phenylhydrazon, react with various olefins and acetylenes in the presence of triethylamine to give 3-trifluo
