Oxidation of ruthenium(II) and ruthenium(III) porphyrins. Crystal structures of .mu.-oxo-bis[(p-methylphenoxo)(meso-tetraphenylporphyrinato)ruthenium(IV)] and ethoxo(meso-tetraphenylporphyrinato)(ethanol)ruthenium(III)-bisethanol

Metal porphyrin/phenyltrimethylammonium tribromide: High efficient catalysts for coupling reaction of CO2 and epoxides

“…Free-base porphyrins H 2 TPP (5,10,15,20-tetraphenylporphyrin) [30], H 2 TMPP (5,10,15,20-tetra-o-methoxyphenylporphyrin) [31], H 2 TNPP (5,10,15,20-tetra-o-nitrophenylporphyrin), H 2 TAPP (5,10,15,20-tetra-o-aminophenylporphyrin) [32], Fe III (TPP)Cl, Mn III (TPP)Cl [33,34], Ru(TPP)(PPh 3 )Cl [35][36][37] were synthesized, purified and characterized following the procedures of literatures described above.…”

17O NMR study of oxo metalloporphyrin complexes: Correlation with electronic structure of M O moiety

“…[Ru(II)(P)(CO)(MeOH)]: This compound was prepared by a literature method [46]. The free base of porphyrin was refluxed with triruthenium dodecacarbonyl in decaline under nitrogen for 4 h. The crude product was purified on a neutral alumina column by elution with dichloromethaneacetone(4:1) and was recrystallized from dichloromethanemethanol.…”

Oxygenation by Ruthenium Monosubstituted Polyoxotungstates in Aqueous Solution: Experimental and Computational Dissection of a Ru(III)–Ru(V) Catalytic Cycle

“…It is worth noting that dimerization through m-oxo bridges is a well-recognized feature in porphyrin chemistry, being responsible for catalyst deactivation. [104] This observation highlights a further analogy between the transition metal substituted POMs and the bio-inspired mechanisms of metalloporphyrins.…”
