Synthesis of Sulfonylhydrazine-1,2-dicarboxylates from Thiols and Dialkyl Azodicarboxylates

1-Sulfonylhydrazine-1,2-dicarboxylates are efficiently prepared via nucleophilic addition of thiols/thiophenols to dialkyl azodicarboxylates and subsequent oxidation with MCPBA. The protocol represents the first application of sulfenylhydrazines as precur

N,N-Disubstituted sulfonyl hydrazines

N,N'-disubstituted sulfonyl hydrazine with the following structural formula are disclosed: wherein the R1 and R2 groups are the same or different and are either --COOR3 or --CONHR4. These novel compounds are useful as high temperature blowing agents for gas-expandable polymers.
