Abstract

Abstract The thermal reactions of 4-chloro-3-coumarinyl N, N-dialkyldithiocarbamates 2–4 and 3-nitro-4-coumarinyl N-phenyldithiocarbamate, 9, afforded the novel heterocyclic systems, eg bis-6H-1-benzopyrano [4, 3-b] 1, 4] dithiin, 7, and bis-6H-1-benzopyrano [4, 3- b][1, 4] thiazine, 14. A possible mechanism of the formation of the reaction products is discussed.
