Reactions of Aromatic Nitriles with Diacyl Dichlorides
Herrmann, D.,Ehrenberg, D.,Podeschwa, K.
, p. 151 - 154 (2007/10/02)
Dicarbonic acid dichlorides react with aromatic nitriles in the presence of SbCl5 to give dicationic bis(1,3,5-oxadiazinium) salts 1.Reaction of 1 with ammonia or hydrazine yields derivatives of bis(1,3,5-triazine) (2) or bis(1,2,4-triazole) (3).
