The 1-thia-3,4-diazolidine-2,5-dione functional group was shown to yield azo compounds upon photolysis.This photoreaction when combined with the known ability of this group to react in a Diels-Alder fashion or as a dinucleophile toward alkylating agents greatly increases the utility of this functionality.The dual reactivity of this group was demonstrated in the synthesis of a number of 3,4-dialkyl-1-thia-3,4-diazolodone-2,5-diones.The photolysis of these compounds produced either thermally stable cyclic azo compounds or the decomposition products of thermally unstable azo compounds.
Cinetique de la reaction d'oxydation de la monomethylhydrazine par la monochloramine

The kinetics of monomethylhydrazine oxidation by monochloramine has been investigated in terms of concentrations, pH from 11 to 13 and temperature in the range 293-308 K.The overall reaction, first order in both reagents, is the result of two competitive steps: - the first being pH independent; - the second accelerated by decreasing pH.The energy of activation for each step has been derived fom our results.In the solution and with an excess of methylhydrazine, formaldehyde monomethylhydrazone CH3NHNCH2 has been identified using mass spectrometry as a final product of the reaction.Other compounds: CH3Cl and CH3OH are also observed but the mechanism of their production is not still clearly established.A simple interpretation of the kinetic result is also proposed.
Ureas as Amine Substrate for Hydrazine and Alkylhydrazine Synthesis---Reaction of Chloramine with Monomethylurea and Formation of 1-Methyltriazane
Prakash, Hari,Sisler, Harry H.
, p. 825 - 828 (2007/10/02)
Reaction of chloramine with monomethylurea has been shown to yield monomethylhydrazine and several side products, e. g., formaldehyde monomethylhydrazone, 1,1-dimethylhydrazine, methyliminotarazane, and methanol, originating from the further oxidation of monomethylhydrazine with chloramine.Evidence for the existance of 1-methyltriazane, CH3NHNHNH2, is presented for the first time.
