Abstract
Anilines and ethyl vinyl ether can be combined in a safe continuous-flow process to achieve efficient and mono-selective formal α-arylation of acetaldehyde. The mild non-basic reaction conditions of this method allow for high functional group tolerance. This process also provides means for a safe and scalable generation of aryldiazonium salts and enables preparation of an array of synthetically valuable monoarylated acetaldehydes.
