N,N-dialkyl-N′-chlorosulfonyl chloroformamidines 1 reacted with 4-substituted urazoles 2 to give [1,2,4]triazolo[1,2-b] [1,2,3,5]thiatriazoles 3 in a selective 1,2-NN dinucleophilic mode of reaction.The reaction of 1 with N1-substituted pyrazol-5-ones 4 afforded pyrazolo[4,3-e][1,4,3] oxathiazines 5 via selective 1,3-CCO dinucleophilic substitution. Compounds 3 and 5 were the sole products isolated from the respective reactions and both represent new ring systems. CSIRO 2010.

A rapid and simple method for the preparation of 4-substituted 1-ethoxycarbonyl semi[0-9] carbazide is reported. The reaction is carried out under microwave irradiation by the reaction of five different isocyanates with ethyl carbazate.
