Abstract

Treatment of Ru(TMP)(CO) with m-CPBA in CH₂Cl₂/EtOH afforded Ru (TMP)(OH)₂, isolated as air-stable violet crystals. Ru(TMP)(OH)₂ in paramagnetic (μ_eff ca 2.7 B.M.) and displays broad ¹H NMR signals with paramagnetic isotropic shifts. The IR spectrum shows a band at 760 cm^-1 assignable to the RuO stretch. Ru(TMP)(OH)₂ is capable of catalysing aerobic epoxidation of alkenes under mild conditions.
