Abstract

Chemistry Chemistry, Organic Physical Sciences Science & Technology
Thiosemicarbazides 5 (yields 50-97%) and N-hydroxythioureas 6 (yields 71-99%) of variable substitution patterns are prepared efficiently by reactions of 1-(thiocarbamoyl)benzotriazoles 4a-i with hydrazines or hydroxylamines, respectively.
