Synthesis and chemical reactivity of new zinc porphyrin diazoacetates catalyzed by ruthenium and iron porphyrins

Zinc porphyrin diazoacetates were synthesized from the corresponding bromoacetates by treatment with N,N’-ditosylhydrazine in ∼70% yield. The transfer of carbenoids derived from the porphyrin diazo compounds catalyzed by metalloporphyrins (Ru,Fe) undergoes dimerization, cyclopropanation, N-H and S-H insertion reactions, respectively
