Abstract
Starting from readily available 2‐substituted‐4‐formylthiazoles and selenazoles, a series of 4‐(2‐aryl‐4‐selenazolyl)‐1,2,3‐selenadiazoles I and 4‐(2‐substituted‐4‐thiazolyl)‐1,2,3‐selenadiazoles II were prepared. Pyrolysis of compound II afforded (2‐substituted‐4‐thiazolyl) acetylenes VII. Addition of potassium hydroxide pellets to an alcoholic solution of II gave 2‐substituted‐1,4‐diselenafulvenes VIII. Decomposition of compound II with base followed by the addition of carbon disulfide gave 5‐substituted 2‐thioxo‐1,3‐thiaselenoles XI.Keywords
