Abstract
The C2H4 + Cl2 addition reaction has been studied from ab initio SCF calculations, assuming a perpendicular approach of Cl2 along the C2v axis of C2H4 and an intermediate ionic state C2H4 Cl+ + Cl-. It is found that, in gas phase, the energy of C2H4Cl+ + Cl- is much to high for a chemically possible intermediate state; the interaction with solvent molecules may allow the reaction according to this path. The potential energy curve is drawn for this first step of the reaction: within the accuracy of our calculations, no transition state appears in gas phase; the solvent effect is discussed, showing that one or several transition states may occur in solution.
