Oxidative Coupling of CH-acid Compounds with p-Phenylenediamines. VII. Synthesis and Oxidative Coupling of 5-Hydroxy-naphth[2,1-d] 1,3-oxathiol-2-ones5-Hydroxy-naphth[2,1-d]1,3-oxathiol-2-ones with different substituents 1-21 were synthesized using the following procedures: Condensation of substituted naphthoquinones-1,4 with thiourea (A); electrophilic substitution of 5-hydroxy-naphth[2,1-d]1,3-oxathiol-2-one (B); Fries-reaction of 5-acyloxy- and 5-N-phenylcarbamoyloxy-naphth[2,1-d]1,3-oxathiol-2-ones (C). Oxidative coupling of the compounds with N,N-diethyl-quinone-1,4-diimine yielded thiazine dyes.
