چکیده

Ni-catalyzed carboxylation of the C(sp(3))-Cl bond with CO2 in the presence of MgCl2 was theoretically investigated. MgCl2 plays three crucial roles in stabilization of a Ni(I)-CO2 adduct and acceleration of the CO2 insertion as a non-innocent additive and the one-electron reduction process as one kind of reagent.

The crucial role of a Ni(I) intermediate in Ni-catalyzed carboxylation of aryl chloride with CO2: a theoretical study.

In Ni(0)-catalyzed carboxylation reaction of aryl chloride with CO2, the formation of a Ni(I) species is crucial, because the CO2 insertion into the Ni(I)-Ph bond easily occurs but that into the Ni(II)-Ph bond cannot. This is a key point of this successful carboxylation reaction.

Ni-Catalyzed direct 1,4-difunctionalization of [60]fullerene with benzyl bromides.

A new Ni-catalyzed direct 1,4-difunctionalization of [60]fullerene with various benzyl bromides has been developed. The use of a DMSO additive combined with a nickel catalyst is indispensable for the formation of 1,4-dibenzyl fullerenes with a variety of functional groups. The reaction proceeds through the formation of a fullerene monoradical species.

A novel and efficient procedure for the preparation of benzyl alcohol by hydrolysis of benzyl chloride catalyzed by PEG1000-DAIL[BF4]/Fe2(SO4)3 under homogeneous catalysis in aqueous media

In this work, benzyl alcohol was obtained in 96% excellent yield by hydrolysis of benzyl chloride catalyzedby the recyclable temperature-dependant phase-separation system that comprised the ionic liquid PEG1000-DAIL[BF4], toluene and ferric sulfate under homogeneous catalysis in aqueous media. This novel methodnot only enhanced the yield, but also made the operating units easy workup. The catal...
