摘要：
The reaction of vinyl fluoride with CN- has been studied by using the DFT B3YLP/6-31 + G(d) method. Topological features of the electron density distribution p(r) and the analysis of the Laplacian concentration -del(2)p(r) have also been utilized for describing this reaction. The results show that this nucleophilic substitution is mainly of rr attack with a barrier height of 14.8 kcal mol(-1) which is 17.91 kcal mol(-1) more favourable than the sigma attack.
