摘要
采用密度泛函方法在B3LYP/6-311G(2d,p)水平上研究了CH_3CHF_2与VO_2^+反应生成CH_2=CF_2(H_2消除反应),CH_2=CHF(HF消除反应)和CH_3CFO的机理.计算结果表明以上三种反应中,H_2消除反应最容易发生.计算结果证明了相邻碳原子上的氢原子有利于C-F键的断裂.
Formation mechanisms of tion) and CHaCFO between singlet CH= = CF2 ( H2 elimination reaction) , CH2 = CHF ( HF elimination reac- VO2 and CH3CHF2 were investigated by using density functional theory (DFT) methods at B3LYP/6 -311 G (2d, p) level. Calculation results indicate that formation of CH2 = CHF ( HF elimination reaction) is the most preferred reaction route among the above - mentioned three reaction chan- nels. Calculation results confirm that the interaction of a H atom on an adjacent carbon can lower the activation barrier for the cleavage of the C - F bond.
