Triplet species from dihydroipyrrolo[3,4-d]pyridazines, the diazene precursors of N-arenesulfonyl-3,4-dimethylenepyrroles

In contrast to the photolyses of N-methyl- or N-pivaloylpyrrolo[3,4]dihydropyridazines in low-temperature matrices, which give the blue, ESR-inactive singlet 3,4-dimethylenepyrrole biradical at all wavelengths, the photolyses of the N-arenesulfonyl deriva
