Anodic Substitution Reaction of Carbamates in a Flow Microreactor Using a Stable Emulsion Solution

An anodic substitution reaction in a flow microreactor using a stable emulsion solution prepared by tandem acoustic emulsification is demonstrated for the first time. The emulsion solution facilitated the selective anodic oxidation of carbamates, and the α-substituted products were ejected from the flow reactor to suppress overoxidation, resulting in an increase in the current efficiency for the desired reaction.
