The Density Functional Theory

In this study, density functional theory calculations, using the M06-2X functional, were performed to investigate the efficiencies of various carbenes in inducing hydrogen abstraction in BH3 through the formation of a Lewis acid–base pair with BH3. The density functional theory results indicate that diamidocarbenes are more efficient in reducing the B–H bond energy of BH3 than diaminocarbenes. Natural bond orbital and combined charge and bond energy analyses were performed to investigate the Lewis acid–base pair formed by BH3 and the title carbenes.
