- Abstract
- This paper reports different examples of Friedel-Crafts acylation of various substrates with dicarboxylic acid chlorides (phthalic, isophthalic, and malonyl synthons) in the presence of the AlCl3-DMF complex as catalyst. When we reacted 2(3 H)-benzothiazolone with phthalic anhydride in the presence of the AlCl3-DMF complex as catalyst, in addition to the product of 6-substitution, 4-(2-carboxybenzoyl) 2(3 H)-benzothiazolone was obtained as a contaminant. This is the first product ever obtained with a 4-substitution in the acylation of 2(3 H)-benzothiazolone.
