Rhodium(II) acetate-catalyzed decomposition of ethyl 2-diazo-3-oxopent-4-enoates results in the formation of either 4-aryl-2-hydroxy-naphthoates or β,γ-unsaturated esters. In the latter transformation, the dianion of 4-(diethylphosphono)acetoacetate functions as a propionate homoenolate equivalent.
乙酸铑(II)催化的2-重氮-3-氧杂戊-4-烯酸乙酯的分解导致形成4-芳基-2-羟基萘酯或β,γ-不饱和酯。在后者的转化中,4-(二乙基膦酰基)乙酰乙酸酯的二价阴离子起丙酸酯均烯酸酯当量的作用。
