Stereospecific Epoxidation by Air of Cholest-5-ene Derivatives catalysed by a Ruthenium Porphyrin
Marchon, Jean-Claude,Ramasseul, Renne
, p. 298 - 299 (1988)
A ruthenium porphyrin catalyses the epoxidation of several cholest-5-ene derivatives by air in high yield and with nearly complete β-stereospecificity; C-3-unprotected cholesterol is unaffected, but cholesteryl acetate gives nearly pure (>99percent) 5β,6β-epoxide.
Generation of trans-dioxoruthenium(VI) porphyrins: A photochemical approach

trans-Dioxoruthenium(VI) porphyrin complexes have been developed as one of the best-characterized model systems for heme-containing enzymes. Traditionally, this type of compounds can be prepared by oxidation of ruthenium(II) precursors with peroxyacids an
Ruthenium porphyrin-catalyzed aerobic oxidation of terminal aryl alkenes to aldehydes by a tandem epoxidation-isomerization pathway

(Figure Presented) Catalytic oxidation of 1-alkenes to aldehydes by an epoxidation-isomerization pathway with air or dioxygen as terminal oxidant has been realized for bulky ruthenium(VI) porphyrin catalysts. For the new, recyclable catalyst [RuVI(tmttp)O2], product yields of up to 99% and total turnover numbers of up to 1144 were obtained.
