- Novel azo dye compound
-
A compound represented by formula (I): Formula (I) wherein Z1 and Z2 each are atoms necessary for forming an aromatic ring; V1 and V2 each are a substituent W1 or W2; when at least one V1 is W1, at least one V2 is W2, or when at least one V1 is W2, at least one V2 is W1; r is 1 to 4; s is 1 to 4; M1 is a counter ion; m1 is the number necessary for neutralizing charge; W1 is a hydroxyl, primary- or secondary- or tertiary-amino, acylamino, or sulfonamido group; W2 is a nitro, cyano, alkoxycarbonyl, aryloxycarbonyl, alkyl- or aryl-sulfonyl, carbamoyl, sulfamoyl, alkenyl, alkynyl, aryl, heterocyclic, sulfo, carboxyl, heterocyclic oxy, ammonio, alkyl- or aryl-sulfinyl, alkyl- or aryl-sulfonyl, acyl, or aryl- or heterocyclic-azo group; and the aromatic ring may have a substituent other than V1 and V2.

Quantum-chemical calculations were used to estimate the reactivity of 4-chloro(bromo)- and 3-chlorophthalimides in nitration. It was found by NMR spectroscopy that 4-chloro(bromo)phathalimides undergo stereoselective nitration to give 4-chloro(bromo)-5-ni
