Singlet and triplet states of C2–carbenes in a proton rearrangement
Abstract
The effect of singlet–triplet splitting in C2–carbenes on the intermolecular proton rearrangement with minimum activation energies was stated by quantum chemical calculations. It is shown that energy barriers of the proton rearrangement by 1→2 shift mechanism correspond to intersections of potential surfaces of singlet states for vinylidene singlet and the nearest triplet states for ethylidene.
