A new-type oxidation-reduction condensation by using 2,6-dimethyl-1,4-benzoquinone (DMBQ), carboxylic acids and in situ formed alkoxydiphenylphosphines (1) including the bulky alkoxy group-substituted ones proceeded smoothly to afford the corresponding carboxylic acid esters in good to high yields. Alkoxydiphenylphosphines were formed in situ by treating either N,N-dimethylaminodiphenylphosphine (Ph2PNMe2)
使用 2,6-二甲基-1,4-苯醌 (DMBQ)、羧酸和原位形成的烷氧基二苯基膦 (1) 的新型氧化还原缩合反应顺利进行,得到相应的羧酸酯的产率很高。烷氧基二苯基膦是通过用伯醇或仲醇处理 N,N-二甲基氨基二苯基膦 (Ph2PNMe2) 或用伯醇、仲醇和叔醇的锂盐处理氯二苯基膦原位形成的。
