Abstract: | The straightforward reaction of 2‐bromopyridine with a PH3/H2 system (generated from phosphorus red and aqueous alkali) in the superbasic KOH/DMSO/(H2O) suspension under mild conditions (70°C, 1.5 h, atmospheric pressure) affords selectively and cleanly tris(2‐pyridyl)phosphine in 50% yield; no admixtures of the expected primary and secondary pyridylphosphines were observed in the crude product. © 2012 Wiley Periodicals, Inc.
