Novel trifluoromethylated spiro-1,3,4-thiadiazoles via [3+2]-cycloadditions of 2,3-diphenylcyclopropenethione with selected in situ-generated nitrile imines derived from trifluoroacetonitrile

The in situ-generated N-aryl nitrile imines derived from trifluoroacetonitrile react efficiently with 2,3-diphenylcyclopropenethione to give spirocyclic 1,3,4-thiadiazole derivatives as products of a regio- and chemoselective [3+2]-cycloaddition in good t

Mannich reaction of trifluoroacetaldehyde hydrazones: A useful entry to trifluoromethyl substituted heterocycles

NH-aryl hydrazones derived from trifluoroacetaldehyde hemiacetal may be involved in efficient Mannich type reactions with formaldehydes and aromatic aldehydes. The resulting hydrazones are useful building blocks for the preparation of trifluoromethyl substituted heterocycles as shown by a straightforward preparation of 1,2-diazine derivatives under heating with β-ketoesters.

Expected and unexpected results in reactions of fluorinated nitrile imines with (cyclo)aliphatic thioketones

A series of (cyclo)aliphatic thioketones have been tested towards trifluoroacetonitrile imines, generated in situ via base-induced dehydrohalogenation of the respective hydrazonoyl bromides. Typically, non-enolisable thioketones yielded exclusively 3-trif
