Pd-catalyzed couplings involving several heteroaromatic halides (bromides and chlorides) as well as boronic acids can be done under exceedingly mild conditions (between rt and 40 degrees C) in pure water using commercially available Pd catalysts and PTS, a nanomicelle-forming amphiphile.
Lipshutz et al. (Tue,) studied this question.
