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.
