Journal ArticleDOI
Synthesis, characterization and reactivity of a novel ruthenium(II) complex containing polypyridyl ligand
TL;DR: In this article, a mechanism involving formation of [RuII(trpy)(pic)(H2O)]+ (1) type of radicaloid intermediate as an active intermediate responsible for epoxide formation is proposed for the catalytic epoxidation process.
Journal ArticleDOI
Asymmetric epoxidation of alkenes using a mixed-ligand complex of ruthenium(III) containing a sugar-based ligand

TL;DR: In this paper, a mixed-ligand ruthenium(III) catalyst complex, [Ru III (TDL*)(bipy)(H 2 O)]Cl ( 1 )(TDL*) = N -3,5-di-( t -butyl)salicylidine- d -glucosamine; bipy = 2,2,2′-bipyridine, and 1,2-dihydronaphthalene were effectively converted to their organic epoxides with moderate enantioselectivity (37-
Journal ArticleDOI
Oxidation of catechol and l-ascorbic acid by [RuIII(tpy)(pic)(OH)]+ (tpy = 2,2′6′,2″-terpyridine; pic− = picolinate): Kinetic and mechanistic studies
TL;DR: In this article, an associative interchange mechanism was used to interpret the spectral and kinetic data and activation parameters of the reaction of catechol to benzoquinone and ascorbate to dehydroascorbic acid.
Journal ArticleDOI
Synthesis and catalytic activity of a novel ruthenium(III) complex containing a sugar-based ligand
TL;DR: The mixed-ligand complex [Ru III (TDL)(bipy)(H 2 O)] + ( 1 ) as mentioned in this paper was shown to catalyze the epoxidation of styrene and oxidize styrene to 1-indanol in dichloromethane using t -BuOOH as a terminal oxidant.
Journal ArticleDOI
[RuIII(medtra)(H2O)] (medtra = N-methylethylenediaminetriacetate) complex – A highly efficient NO inhibitor with low toxicity
TL;DR: Stopped-flow kinetic measurements were used to compare the reactivities of [Ru(medtra)(H2O)] with NO in aqueous solution at 15°C, pH 7.2 as mentioned in this paper.
