A Novel and Chemoselective Preparation of Chlorosulphonyl-containing Azo-dyes with Phosphoryl Chloride-N,N-Dimethylacetamide

Azo dyes containing a chlorosulphonyl group (1b)-(10b) have been prepared by the reaction of the corresponding sodium sulphonates (1a)-(10a) with phosphoryl chloride-N,N-dimethylacetamide (in acetonitrile); the chemoselectivity of this reagent is superior
