Abstract

The 1, 2-naphthoquinonediazide-(2)-6-and-7-sulfonic acid esters (7c, 7d) have been synthesized for first time starting from the 1-naphthyl-amine-6-and-7-sulfonic acids (1c, 1d), respectively, via Bucherer reaction, nitrosation, reduction, diazotation, sulfochlorination, esterification. The synthesis of the corresponding 8-sulfonic acid ester 73 was not successful by this way. On photolysis the 1, 2-naphthoquinonediazide-(2)-6-and-7-sulfonc acid ...
