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 is paramagn etic (mu(eff) ca 2.7 B.M.) and displays broad H-1 NMR signals with par amagnetic isotropic shifts. The IR spectrum shows a band at 760 cm-1 a ssignable to the Ru-O stretch. Ru(TMP)(OH)2 is capable of catalysing a erobic epoxidation of alkenes under mild conditions.
