在Pd II / Cu(II)羧酸盐/ CO的存在下,依靠双重C–N键裂解策略,可实现具有高结构和功能多样性的胍衍生物的高效非酶分解为苯胺产物。在这种分解过程中,Pd II物质,Cu(II)羧酸盐和CO的协同作用不仅提供N-酰化剂,而且还提供引发该C–N键裂解序列的引发剂。目前的结果表明,Pd II / Cu(II)羧酸盐/ CO系统为非反应性C–N单键的高选择性裂解提供了一种方便实用的方法。

nonenzymatic decomposition of guanidine derivatives with high structural and functional diversity into anilide products is achieved in the presence of PdII/Cu(II) carboxylates/CO, relying on a dual C–N bonds cleavage strategy. In this decomposition process, the cooperative action of PdII species, Cu(II) carboxylates, and CO provides not only the N-acylating agents but also an initiator to trigger this
