Subject 2-aminobenzenethiol

The tin(II) chloride reduction of [Re04]- and 2-aminobenzenethiol (N—S) in hydrochloric acid gives a red-brown complex ReO(OH)(N—S)2 which is air sensitive and converts to green Re203(N —S)4.372 The macrocyclic complex Re203(L)2 (LH2 = octaethylporphine) has been the subject of a preliminary report but few details are available.375... 

It appears that the zinc chloride generated in the reaction inhibits further condensation with the product (Scheme 43) but the presence of pyridine may neutralize the effect caused by it (Scheme 44). This reaction was extended to a number of substituted 2-aminobenzenethiols in order to prepare substituted 6-chlorobenzophe-nothiazin-5-ones (88MI1, 93PS(80)23). Some of the resulting compounds were subjected to reduction, methylation and acetylation and a number of these products were screened for their antimicrobial activity.
