Abstract

The reaction of thiophosgene with α-diazocarbonyl compounds produced mixtures of 1, 2, 3- and 1, 3, 4-thiadiazoles, in which the latter predominated, irrespective of whether the bis (α- diazoacyl) mercury derivatives or the free diazo compounds were used. In contrast, ethyl chlorodithioformate gave exclusively 1, 3, 4-thiadiazoles with α-diazocarbonyl compounds in the presence of triethylamine and only 1, 2, 3-thiadiazoles when the bis (α-diazoacyl) ...
