Conformational analysis of N,N'-dinaphthyl heterocyclic carbenes: imidazol-2-ylidenes and imidazolin-2-ylidenes
The paths connecting the stationary points of tesseract (four-dimensional hypercube) have been explored. The minimum energy conformations and the different transition states of N,N′-dinaphthyl imidazol-2-ylidenes and imidazolin-2-ylidenes have been calculated. The available experimental results were conveniently reproduced. The dimerization of carbenes to enetetramines has also been calculated.
