Reaction pathways leading to products of the reactions in the system [CHCl]2+ + D2 (CHCl+, CCl+, CHDCl+, HD2+, D2+, as observed experimentally) were studied by the CCSD(T)/cc-pVTZ method. Energies of located stationary points on the potential energy hypersurface were refined by the G2 method. Both isomers of the reactant dication CHCl2+, HCCl2+ (with H bonded to C) and CClH2+ (with H bonded to Cl) were taken into consideration. The calculated reaction pathways were of importance in the interpretation of experimental beam scattering data. Heats of formation of the reactant dications HCCl2+ and CClH2+ and of all relevant products ions (CCl+, HCCl+, CClH+, H2CCl+, HCClH+) were calculated.
