摘要: 用限制的HF/3-21G和HF/6-31G*优化乙烯醇锂的几种可能构型,比较了它们的稳定性.用限制的HF/3-1G,从乙醛开始,探讨了气相反应生成乙烯醇锂的机理,并在MP2水平上用6-31G*基组计算了反应热.

关键词: 乙烯醇锂, 结构优化, 反应机理, 从头算

Abstract: Two possible geometries of CH2=CH-OLi and transition states between them were optimized by using RHF/3-21G and RHF/6=31G*. The stability of the two structures were discussed. The mechanism of producing CH2=CH—OLi from CH3—CH(=O) and Li-OH in gas phase was investigated under RHF/3-21G level. We found that the concerted mechanism was preferred. We also calculated the reaction heat by using 6-31G* basis sets at MP 2 level.
