中性的双环胍1，3，4，6，7，8-六氢-2H-嘧啶并[1，2-a]嘧啶（hppH）通过亚胺氮与Cu（I）卤化物配位，配合物被分子内NH +4稳定。X相互作用（X = Cl，Br）或部分解离（X = I）在固态;在所有情况下，在溶液中观察到fluxional行为。选择的配合物已被测试作为甲基丙烯酸甲酯聚合的催化剂。
The neutral, bicyclic guanidine 1,3,4,6,7,8-hexahydro-2H-pyrimido[1,2-a]pyrimidine (hppH) coordinates to Cu(I) halides via the imine nitrogen, and the complexes are stabilized by intramolecular NH...X interactions (X = Cl, Br) or are partially dissociated (X = I) in the solid state; in all cases, fluxional behavior is observed in solution. Selected complexes have been tested as catalysts for the polymerization of methyl methacrylate.
