An electrochemical coupling of organic halide with aldehydes, catalytic inchromium and nickel salts. The Nozaki-Hiyama-Kishi reaction

[GRAPHICS] Electrochemical arylation of arenecarboxaldehydes using an iron sacrificial anode in the presence of chromium and nickel catalysts afforded the corres ponding arylated secondary alcohols in moderate to good yields, The chromiu m and nickel salts as catalysts are obtained by oxidation of a stainless st eel rod during a preelectrolysis in 7% and 3%, respectively. The process wa s also applied to the addition of vinyl halide, allyl acetate, or alpha -ch loroester to aromatic aldehydes.
