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-dibromofluorene derivative along with a 2,7-fluorenylenebisHOMSi reagent.
