Abstract

A visible-light-driven photocatalytically active nanocrystalline TiO₂ was prepared by surface modification with a cobalt–ascorbic acid complex. The photocatalyst exhibited high activity and excellent chemo-, diastereo-, and stereoselectivities in the aerobic epoxidation of olefins under visible-light irradiation in the absence of a reducing agent. The catalyst proved efficient and could be recycled at least five times.

Key words

11 Typical Procedure and Reusability of Catalyst: To a mixture of norbornene (1 mmol) and TiO₂/AA/Co nanohybrid (0.2 mol%) in EtOAc (1 mL) was added NHPI (15 mol%, 0.024 g) and the reaction mixture was stirred under 1 atm O₂ (5−7 mL/min) and visible light at 60 °C for 4 h. After completion of the reaction, TiO₂/AA/Co nanohybrid was separated by centrifugation followed by decantation (3 × 5 mL EtOAc). The isolated solid-phase TiO₂/AA/Co nanohybrid was washed with EtOH then dried under reduced pressure and reused for the next run.
