  GRAPHICAL ABSTRACT ABSTRACT The synthesis and characterization of new N-heterocyclic carbene platinum(II) complexes functionalized with a polyether chain and silyl group are described. In addition, their application towards the catalytic hydrosilylation of unsaturated carbon–carbon bonds, including alkenes, alkynes, vinyl ether, and unsaturated esters, is reported. These new complexes exhibit both

  A series of carboxyl-functionalized imidazolium salts were synthesized. Hydrosilylation reaction of carboxyl-functionalized imidazolium salts (1b–4b, 1c–3c) exhibited higher levels of styrene conversion and higher levels of β-adduct selectivity. In particular, no ethylbenzene as hydrogenation product could be yielded at all when Rh(PPh3)3Cl/carboxyl-functionalized imidazolium inner salts (1c–3c), respectively

  合成了一系列羧基官能化的咪唑鎓盐。羧基官能化的咪唑鎓盐（1b - 4b，1c - 3c）的氢化硅烷化反应显示出更高的苯乙烯转化率和更高的β-加合物选择性。特别地，当分别使用Rh（PPh 3）3 Cl /羧基官能化的咪唑鎓内盐（1c - 3c）作为催化剂时，根本无法得到乙苯作为氢化产物。Rh（PPh 3）3Cl /羧基官能化的咪唑鎓盐催化剂体系可以重复使用，而催化活性没有明显损失。

  A series of polyethylene glycol-functionalized imidazolium ionic liquids has been prepared and characterized. These ionic liquids have been successfully applied in the hydrosilylation of alkenes catalyzed by rhodium complexes. The effects of the length of the polyether chain, the amount of ionic liquid, and the reaction temperature on the catalytic performance of hydrosilylation have been investigated. Furthermore, the catalytic system has been tested for the hydrosilylation of different alkenes with triethoxysilane. The new catalytic system exhibits both excellent catalytic activity and selectivity under low-temperature conditions. The catalyst system could be recycled five times with slightly deactivation.
