It has been established that the electrolysis of α-substituted phosphonates (I) on Pt or glassy carbon cathodes involves the cleavage of activated C-H bond with the formation of the carbanion (II) which further reacts with the carbonyl compound (III) to form olefins (IV) in satisfactory yields.
已经确定,在
铂或
玻璃碳阴极上电解α-取代的
膦酸酯(I)涉及裂解活化的CH键并形成碳负离子(II),该碳负离子进一步与羰基化合物(III)反应形成烯烃。 (四)产量令人满意。
