Aldol condensations of aldehydes with ketones catalyzed by the first-row transition metal(II) complexes have been widely studied. Complexes of Co(II), Ni(II), Cu(II), and Zn(II) acetates with 2,2′-bipyridine were effective catalysts to afford cross-aldol condensation products, α,β,-unsaturated ketones, in high yields without any self-condensation products. The reaction of 2-butanone, unsymmetrical aliphatic
已经广泛研究了由第一排过渡金属 (II) 配合物催化的醛与酮的羟醛缩合反应。Co(II)、Ni(II)、Cu(II) 和 Zn(II) 醋酸盐与 2,2'-联吡啶的配合物是提供交叉羟醛缩合产物 α,β,-不饱和酮的有效催化剂。没有任何自缩合产物的高产率。2-丁酮(不对称脂肪族酮)与苯甲醛的反应发生区域选择性,得到碱催化型产物。
