Fluorine-containing heterocycles: XV. Reactions of polyfluorobenzoyl isothiocyanates with aminoazines and aminoazoles
摘要:
Reactions of tetra- and pentafluorobenzoyl isothiocyanates with aminoazoles and aminoazines led to the formation of fluorinated 1,3-benzothiazin-4-ones which reacted with cyclic amines in different ways. Replacement of the N=C=S fragment was observed in some reactions of polyfluorobenzoyl isothiocyanates with nucleophiles.

Reactions of 2-benzoylmethylbenzimidazole with tetra- and pentafluorobenzoyl chlorides afford fluorine-containing 6-benzoyl-7H-benzimidazo[3,2-a]quinolones. 2-Cyanomethyl- or 2-benzoylmethylbenzimidazole reacts with tetra(penta) fluorobenzoyl isothiocyanates to give fluorine containing 1,3-benzothiazinones, which differently behave in reactions with cycloalkylimines.
