镁/镧复合氧化物是一种有效的多相催化剂，用于醛、亚胺与重氮乙酸乙酯(EDA)在室温水中的羟醛缩合反应，以较高的产率得到相应的β-羟基-α-重氮羰基化合物和β-氨基-α-重氮羰基化合物。催化剂被回收和重复使用几个循环，具有稳定的活性。
Magnesium/lanthanum mixed oxide is an effective heterogeneous catalyst for aldol-type condensation of aldehydes and imines with ethyl diazoacetate (EDA) at room temperature in water to afford corresponding beta-hydroxy-alpha-diazo carbonyl compounds and beta-amino-alpha-diazo carbonyl compounds in good yields. The catalyst is recovered and reused for several cycles with consistent activity.
