Ruthenium corroles

The earliest report of a ruthenium corrole complex appeared in the literature in 2000 [64], and the most recent in 2003 [179]. The initial report described the synthesis of the face-to-face dimer [Ru(hedmc)]2 (Fig. 15), synthesized by reaction of P hedmc with [Ru(cod)Cl2]2 (where cod = 1,5-cyclooctadiene) in 2-methoxyethanol in the presence of trimethylamine. This complex displays an extremely blue-shifted Soret electronic absorption system, with minimal Q-band intensity. The Ru-Ru bond distance is 2.166(1) A the Ru atoms are displaced toward one another and out of the corrole plane by 0.514(4) A. Based on the MO description of Collman and Arnold...

Epoxidation of alkenes with iodosylbenzene can be effectively catalyzed by the analogous salen or chiral Schiff base complexes of manganese(in), ruthenium(II), or ruthenium(III). For example, the oxidation of indene with iodosylbenzene in the presence of (/ ,5)-Mn-salen complexes as catalysts affords the respective (15,2/ )-epoxyindane in good yield with 91-96% ee [704]. Additional examples include epoxidation of alkenes with iodosylbenzene catalyzed by various metalloporphyrins [705-709], corrole metal complexes, ruthenium-pyridinedicarboxylate complexes of terpyridine and chiral bis(oxazoUnyl)pyridine [710,711].
