Abstract

Cross-coupling reaction of dibromoarenes with HOMSi reagents (organo [2-(hydroxymethyl) phenyl] dimethylsilanes), or alternatively bromoarenes with arylene-bisHOMSi reagents, proceeded smoothly in the presence of a Pd catalyst and a weak base, and ter-or quaterarenes are produced in excellent yields. The present reaction was successfully applied to polyarylene synthesis using 4, 7-dibromobenzothiadiazole or a 2, 7- ...
