Chloromethyleneiminium salts formation

Formates have been prepared by the reaction of chloromethyleneiminium salts with derivatives of alcohols and phenols. Yields are generally good. ... [Pg.790]

Wallach was the first (1874) to report on the transformation of carboxylic acid amides to amide chlorides by treatment with PCls various types of amides were converted by this reagent to chloromethyleneiminium chlorides (30 equation lg). - > Side reactions can include the a-chlorination of the amide chloride. If excess PCIs is used, the formation of iminium salts with complex ions (31) has been reported. The very labile bromomethyleneiminium bromides (32 equation 19) can be obtained by action of PBrs on tertiary amides. The iodomethyleneiminium salt (33) was prepared from DMF and diphosphorus tetraiodide in CS . ... [Pg.495]
