Regioselective Syntheses of 1,4- and 1,6-Dicarbonyl Compounds via Photoredox-Based Oxidative Heterocoupling of Enolsilanes with Oxygen as an Oxidant.

ABSTRACT

A photoredox-based oxidative heterocoupling of enolsilanes to the corresponding 1,4- and 1,6-dicarbonyl compounds was developed by using Mes-Acr+BF4- as the photocatalyst, and oxygen was used as the oxidant. This newly developed chemistry adheres to the principles of atom economy, step economy, and redox economy, making it a concise and efficient method.
