Abstract

A simple process for the synthesis of phenyl-2-propanone is described based on a one-step electrochemical acylation reaction, involving the direct electroreductive coupling of benzyl bromides and acetic anhydride in a micro-flow electrolysis cell, equipped with micro-gap Pt electrodes. The technique offered yields typically in excess of 80% with corresponding high levels of product selectivity. The electrochemical process was also scaled-up by connecting four identical micro electrochemical cells in parallel to increase product throughput.
