Abstract

Compounds having the general formula <FORM:0647759/IV (b)/1> in which R is an alkyl, aryl or aralkyl group, X and X1 are zero or a small integer and n, n1 and m are integers, are prepared by reacting a stilbene compound of the general formula <FORM:0647759/IV (b)/2> with an acyl chloride having the formula <FORM:0647759/IV (b)/3> Compounds specified are sodium 4,41-di-p-methoxybenzoylaminostilbene - 2,21 - disulphonate and the corresponding o-methoxy compound; sodium 4,41-di-p-ethoxybenzoylaminostilbene - 2,21 - disulphonate; sodium 4,41 - di - 311,411,511 - trimethoxybenzoylaminostilbene - 2,21 - disulphonate; sodium 4,41 - di - p - phenoxybenzoylaminostilbene - 2,21 - disulphonate; sodium 4,41-di-p-benzyloxybenzoyl - aminostilbene - 2,21 - disulphonate; sodium 4,41 - di - 411 - methoxy - 311 - methylbenzoylaminostilbene - 2,21 - disulphonate; sodium 4,41 - di - p - methoxybenzoylaminobenzoylaminostilbene - 2,21 - disulphonate; and sodium 4,41 - di - 311 - acetylamino - 411 - methoxybenzoylaminostilbene - 2,21 - disulphonate. The preparation of sodium 4,41 - di - p - methoxybenzoylaminostilbene - 2,21 - disulphonate, sodium 4,41 - di - p - ethoxybenzoylaminostilbene - 2,21 - disulphonate and sodium 4,41 - di - 411 - methoxy - 311 - methylbenzoylaminostilbene - 2,21 - disulphonate is described, and also the intermediates p-ethoxybenzoic acid, p p-ethoxybenzoyl chloride, 4-hydroxy-3-methylbenzoic acid, 4 - methoxy - 3 - methylbenzoic acid, and 4-methoxy-3-methylbenzoyl chloride.
