Abstract

The dynamic thin film formed in an angled rapidly rotating tube in a vortex fluidic device (VFD) is effective in facilitating multicomponent reactions (MCRs) as photocatalytic or metal-mediated processes. Here, we demonstrate the utility of the VFD by using two known MCRs, an Ugi-type three component reaction and an A³-coupling reaction. The Ugi-type reaction can be done in either confined or continuous-flow modes of operation of the microfluidic platform whereas the A³-coupling reaction was optimized for the confined mode of operation. The examples tested gave excellent yields with short reaction times.
