Abstract

Microflow systems were found to serve as powerful tools for mechanistic studies on reactions involving highly unstable intermediates such as o-bromophenyllithium, which is known to decompose to benzyne very quickly even at-78° C. Precise residence time control and precise temperature control of microsystems are responsible. Based on the information thus obtained, the Br-Li exchange reaction of o-dibromobenzene followed by reactions ...
