2-甲基-1,3-顺丁二烯在Ni(Ⅰ)催化下与苯甲醛反应机理的研究
Theoretical investigation on the reaction mechanism of 2-methyl-1, 3-cis-butadiene with benzaldehyde catalyzed by Ni(I)
摘要
Abstract
The reaction mechanism of 2-methyl-1,3-cis-butadiene with benzaldehyde catalyzed by Ni(I) was studied using the density functional theory at B3LY P/6-31+G* level.The geometric configurations of reactants,intermediates,transition states and products were optimized.Nature bond orbital (NBO) and atoms in molecules (AIM) theories were used to discuss the bond nature and orbital interactions at the same levels.Two possible reaction pathways,IA and IB,were investigated and their activation energies of the limiting steps are 64.20 and 51.63 kJ · mol-1,respectively.The reaction is the rate determining step.From the above results,it can be seen that throughout the course of the reaction the IA and IB channels occur at the same time,but the IB channel has lower activation energy.So IB channel is the main reaction channel in the whole reaction.These points are in agreement with the experimental results.关键词
