n-5 and orthometalated N,N-dimethylbenzylamine, [Pd(o-C6H4CH2NMe2)Cl]2. Its solubility in water is more than ten times higher than that of the related complex without the crown fragment and increases further in the presence of magnesium(II) salts. Potential applications of the newly synthesized palladacycle in catalysis is demonstrated by the example of biomimetic hydrolysis of 4-nitrophenyl 2,3-dihydroxybenzoate
用15-冠-5基序Orthopalladated芳肟在由环钯配体从4'- acetylbenzo-15-冠-5的肟交换产率72%制备和邻位Ñ,Ñ -dimethylbenzylamine,[钯(ø - C 6 H 4 CH 2 NMe 2)Cl] 2。其在水中的溶解度是没有冠状片段的相关配合物的十倍以上,并且在存在镁(II)盐的情况下进一步增加。通过4-硝基苯基2,3-二羟基苯甲酸酯的仿生水解的实例证明了新合成的palladacycle在催化中的潜在应用。已经证明,通过实现分子内通用基本机制可以实现120倍的速率增加。
