[reaction: see text] Electrochemical arylation of arenecarboxaldehydes using an iron sacrificial anode in the presence of chromium and nickel catalysts afforded the corresponding arylated secondary alcohols in moderate to good yields. The chromium and nickel salts as catalysts are obtained by oxidation of a stainless steel rod during a preelectrolysis in 7% and 3%, respectively. The process was also applied to the addition of vinyl halide, allyl acetate, or alpha-chloroester to aromatic aldehydes.
[反应:见正文] 在铬和镍催化剂存在下,使用铁牺牲阳极对芳基甲醛进行电化学芳基化反应,以中等至良好的产率得到相应的芳基化仲醇。作为催化剂的铬盐和镍盐分别通过在7%和3%的预电解过程中不锈钢棒的氧化而获得。该方法也适用于卤化乙烯、乙酸烯丙酯或α-氯酯与芳香醛的加成反应。
