摘要：
MCH2(OH) and CH3OM(M = -, Li, Na) were calculated by means of ab initio method at the MP2/6-31+G* level. The results show that the metals have the ability to localize charge on O in CH3OM(M = Li, Na). MCH2(OH) (M = Li, Na) has four possible structures, among which carbon-oxygen-bridged structure I is the most stable and observable kinetically. For MCH2(OH) (M = Li, Na), the existence of the metal increases the rigidity of the carbon configuration. This may be the reason why MCH2(OR) (M = Li, Na) is widely used in stereo-selective syntheses.
