A novel, three-component CN bond forming reaction is described. Reaction of diazo compounds with both azodicarboxylates and arylamines in the presence of dirhodium acetate catalyst gives good yields of the corresponding aminal with high selectivity and, in most cases, NH insertion side products were suppressed. This is the first example of a CN bond formation from the addition of ammonium ylides to
描述了新颖的三组分CN键形成反应。重氮化合物与偶氮二羧酸盐和芳基胺在乙酸乙二胺四乙酸催化剂存在下的反应以高选择性产生了相应的缩醛的良好收率,并且在大多数情况下,NH插入副产物被抑制。这是从将铵盐加入到偶氮二羧酸盐中形成CN键的第一个例子。
