Cover Picture: Highly Selective Reduction of α, β‐Unsaturated Aldehydes and Ketones under Ambient Conditions using Tetraalkylphosphonium‐based Ionic Liquids (42/2018)

Abstract

The cover picture shows highly selective reduction of cinnamaldehyde to cinnamyl alcohol facilitated in ionic liquids. In this work, a new protocol for selective reduction of α, β‐unsaturated aldehydes and ketones, has been developed in presence of ionic liquids by using NaBH4 as reducing agent. Under optimised conditions in [P6,6,6,14][N(CN)2] ionic liquid, 97% conversion of cinamaldehyde with 100% selectivity to cinnamyl alcohol was achieved with enhanced reaction rates. The reaction protocol is facile and [P6,6,6,14][N(CN)2] ionic liquid was easily recycled without any noticeable loss of activity and selectivity.
