rel results is dubious. For example, a closer inspection reveals that although the shape of the PM3/CI and AM1-CI curves are similar, the actual order of the points is disturbingly different. Thus, although we had expected arenesulfonyl to be more effective than acetyl in diminishing thepreference for the singlet, the PM3-CI calculations reversed this order, predicting that acetyl would be more effective than benzenesulfonyl. Fortunately, our experimental results eventually showed that arenesulfonyl was better for our purpose than aliphatic acyl, although the reasons for this turned out to be more intricate than the simple EWG considerations that had guided our earlier thinking.
