Exposure of (functionalized) aryl chlorides to catalytic quantities of nickel-on-charcoal in the presence of stoichiometric amounts of Me2NH · BH3/K2CO3 in refluxing acetonitrile leads to high yields of reduced arenes. PCBs are also reduced under these conditions. The method is highly tolerant of moisture.
