The reductive coupling of aryl halides to form the corresponding biaryls was effected with high selectivity in water, using formic hydrazide as a reducing agent in the presence of a catalytic amount of Pd/C. Various substituted aryl halides proceed smoothly to afford the corresponding biaryls with good yields in the range of 52%～94%.

Key words: aryl halide, reductive coupling reaction, formic hydrazide, Pd/C, biaryl
