Metal-exchanged clays (M = Rh and Cu) catalyze effectively the reaction of methyl diazoacetate with various aldehydes, affording the corresponding β-keto esters in high yields. They have also been effective in the decomposition of methyl diazoacetate to form metallocarbenes which, in turn, successfully insert into X–H (X = N, O, S, CO2) bonds of a variety of amines, aldehydes, thiols and acids, thereby producing the corresponding esters.
金属交换粘土(M = Rh 和 Cu)能有效催化重氮乙酸甲酯与各种醛的反应,从而以较高的产率获得相应的 β-酮酯。它们还能有效地分解重氮乙酸甲酯,形成金属羰基,而金属羰基又能成功地插入各种胺、醛、硫醇和酸的 X-H(X=N、O、S、CO2)键,从而生成相应的酯。
