  1-Thia-3,4-diazolidine-2,5-dione functionality: a photochemical synthon for the azo group

  摘要：

  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 dinucelophile 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-diazolidine-2,5-diones. The photolysis of these compounds produced either thermally stable cyclic azo compounds or the decomposition products of thermally unstable azo compounds.
