    • Norrby et al, 10b] have shown that it is important to optimize the transition states in solution in nucleophilic attack on cationic (π-allyl)palladium complexes. They found that this is of particular importance for anionic nucleophiles where separated charges are brought together to form a neutral molecule. In the latter cases no transition state was obtained in the gas phase and the energy differencebetween product and starting material was unreasonably large (> 100 kcal mol-1, For ammonia as nucleophile the effect was much smaller, and a transition state could be located at 2 kcal mol-1 and the reaction was essentially thermoneutral with both gas phase and solution models. The latter reaction barrier is increased on solvation but it is still low (8-10 kcal mol -1, In our case we have attack by a neutral molecule on a charged species. All our intermediates and transition states have the same charge, 1) which gave good results in gas phase cal
