Catalyst‐Free Three‐Component Petasis Reactions Accelerated in Microdroplets: Reaction Optimization and Senstive Detection by Mass Spectrometry

The cover feature image illustrates two mail devices, drones (representing sprayed microdroplets) and in-person bulk phase), to deliver a letter the Petasis reaction involving aldehydes, arylboronic acids amines) in sharply different efficiencies. This study supplies not only mild, efficient environmentally friendly methodology constructing aryl amines organic community but also useful derivatization strategy for highly sensitive mass spectrometric detection of aldehydes.
