Density Functional calculations (DFT) have been used to explore the potential energy profiles of H2, CO, and CO2 activation reactions by vinyl carbene structure 1. The reactions of vinyl carbene 1 with CO2 was proposed to yield a variety of possible products (3−5) depending on its selectivity. The DFT calculations established that the proposed reactions of 1 with CO2 proceed in a concerted or stepwise manners to form 3 and 5. However, that of CO reaction occur in only concerted fashion for the proposed products 15 and 16. Furthermore, the compound 1 is found to be most reactive than 5 and 16 towards H2 with the required lower energy barrier. Finally, the most dominant routes are determined to be formation processes of 3, 4, and 10.
