N2 - The gas phase reaction of chloride ion with alkyl chlorides (methyl, ethyl, propyl, i-propyl, i-butyl, t-butyl and neo-pentyl) has been studied by ab initio methods. Geometries of stationary points along the reaction coordinate have been optimized at the MP2/6-31G* level of theory and improved energies have been calculated with the 6-311 + G(2d) basis. Although all reactions are "narcissistic", i.e. reactant and product are identical, it is found that some of the transition structures have unequal CCl bond lengths. The breaking/forming CCl bond for the t-butyl system is significantly longer than for the other alkyl groups, for which the change with increasing steric bulk is as expected.
