Tetradentate N,N,N,N-(diphosphinomethyl)amine ligands and their Pd(II) and Ru(II) complexes were synthesized under a nitrogen atmosphere using Schlenk technique. The synthesized ligands and the complexes were characterized with 1H- and 31P-NMR, FT-IR, TG/DTA, and elemental analysis techniques. Pd(II) Complexes were used as catalysts in Heck coupling reactions and Ru(II) complexes were tried in transfer hydrogenation reactions of acetophenone derivatives. According to the results, L4-Pd(II) complex showed the best catalytic activity in the Heck coupling reaction of p-methylbromobenzene with o-chlorostyrene. It was confirmed that the reduction of bromo and chloroacetophenones in all catalysts the conversions were higher. The results showed that Ru(II) complexes as efficient catalysts and up to 99% conversions was occurred with bromo and chloro acetophenones in K2CO3/isopropyl alcohol media at 80 °C.

Pd（II）和Ru（II）配合物的合成与表征

使用Schlenk技术在氮气氛下合成四齿N，N，N，N- （二膦基甲基）胺配体及其Pd（II）和Ru（II）配合物。用1 H-和31 P-NMR，FT-IR，TG / DTA和元素分析技术对合成的配体和配合物进行表征。Pd（II）配合物在Heck偶联反应中用作催化剂，Ru（II）配合物在苯乙酮衍生物的转移加氢反应中尝试过。根据结果​​，L4-Pd（II）配合物在对甲基溴苯与邻苯二甲酸的Heck偶联反应中表现出最佳的催化活性。-氯苯乙烯。证实在所有催化剂中溴和氯苯乙酮的还原转化率较高。结果表明，在80 ° C的K 2 CO 3 /异丙醇介质中，溴和氯苯乙酮与Ru（II）配合物是有效的催化剂，转化率高达99％。
