Abstract

Abstract : The syntheses of [Ru VI (Por)(NAd)(O)] and [Ru VI (2, 6-F2 -TPP)(NAd)2 ] have been described. [Ru VI (Por)(NAd)(O)] characterised by X-ray crystallography is competent for H-atom abstraction and aerobic alkene epoxidation. Abstract : The syntheses of [Ru VI (Por)(NAd)(O)] and [Ru VI (2, 6-F2 -TPP)(NAd)2 ] have been described. [Ru VI (2, 6-F2 -TPP)(NAd)(O)] capable of catalysing aerobic epoxidation of alkenes has been characterised by X-ray crystallography with RuNAd and RuO bond distances being 1.778(5) Å and 1.760(4) Å (∠O–Ru–NAd: 174.37(19)°), respectively. Its first reduction potential is 740 mV cathodically shifted from that of [Ru VI (2, 6-F2 -TPP)(O)2 ].
