DFT study on the unsaturated silylenoid H2C=SiNaFΧ

The unsaturated silylenoid H2C=SiNaF was studied by using the DFT B3LYP method in conjunction with the 6-31+G(d, p) basis set. Geometry optimization calculations indicate that H2C=SiNaF has four equilibrium configurations, in which the p-complex has the lowest energy and is the most stable structure. Three transition states for isomerization reactions of H2C=SiNaF are located and the energy barriers are calculated. For the most stable one, vibrational frequencies and infrared intensities have been predicted.
