Abstract
Molecular complex 3-methyl-2,4-dinitrothiophene 1,1-dioxide-pyridine gives rise to highly reactive 3-methyl-2,4-dinitrothiophene 1,1-dioxide which is capable of taking up amines at the diene system with subsequent desulfonylation to afford aminodinitrobutadienes. It can also undergo rearrangement into the isomer containing an exocyclic double bond, which is then converted into 3-methylene-4-nitro-1,1-dioxo-2,3-dihydrothiophen-2-ylideneazinic acid ammonium salt.
