钯-多金属氧酸盐催化C－C键生成的研究

Palladium-polyoxometalates-catalyzed C-C Bonds Formation

以制备的钯-多金属氧酸盐作为催化剂,催化通过C-H键官能团化构建C-C键的反应,包括苯与苯乙烯的乙烯化反应以及芳香烃与芳香烃的偶联反应.实验结果表明,在氧化偶联构建C-C键的反应中,催化剂量的多金属氧酸盐可以作为氧化剂使用,此外,还对反应条件(反应压力,反应溶剂,添加剂等)进行了探索,表明反应条件比较温和,反应产率还有待于提高.

Palladium-polyoxometalate was synthesized,and its use as catalyst for C-C formation via C-H bonds functionalization including oxidative coupling of benzene with styrene and oxidative coupling of aryl compound with aryl compound was also examined.From the examination of the catalyst performance,it was found that the catalytic amount of polyoxometalate can use as an oxidant in the reaction.In addition,reaction pressure,solvent,and additive were varied.The study showed that the conditions of C-C formation by palladium-polyoxometalate were mild,but yield has yet to be improved.
