Synthesis, crystal structure, catalytic dimerization and S-H insertion of new porphyrin diazoketones

Abstract : Porphyrin diazoketones were synthesized from the corresponding porphyrin acetyl chloride by treatment with trimethylsilyldiazomethane in 60-80% yield. The solid-state structure of one of the two bisdiazo derivatives (trans isomer) was determined by single-crystal X-ray diffraction analysis. Thiol insertion and cis-selectivity in the coupling reactions of porphyrin diazoketones catalyzed by ruthenium porphyrin were observed.
