摘要1- [2'-(甲氧基羰基)苯基] -3- [4'-X-苯基]三嗪[X = F(1),Cl(2),Br(3)型三嗪的合成与表征,I(4)]作为三叠氮化物配体的前体,用于制备式[Ru 1-(2'-甲氧基羰基苯基)-3-(4'-X-苯基)三叠氮化物}(Cl)(对伞花烃)的配合物)] [X = F(6),Cl(7),Br(8),I(9),CH 3(10)]被报道。通过X射线衍射研究确定了所有四个三氮烯(1-4)以及配合物6、9和10的分子结构。在有碱和无碱存在下,在苯乙酮转移氢化反应中,配合物6-10均作为催化剂进行了测试。在存在碱的情况下获得最佳结果,产率在86–94%的范围内,而即使在不存在碱的情况下,也可以达到42–65%的范围。
