Abstract
It is shown that the bases described in a number of papers and patents as 2,6-dimethyl-, 2,6-diamino-, and 2,6-dimercaptobenzo[1,2-d:4,3-d']bisthiazoles (isomers of linear structure) are actually 2,7-dimethyl-, 2,7-diamino-, and 2,7-dimercaptobenzo [1,2-d:6,5-d']bisthiazoles (isomers of angular structure). The synthesis of the hitherto unknown 2,6-dimethylbenzo[1,2-d:4,5-d'] bisthiazoles is described.
