The stereocontrol of chemical reactions on surfaces is a challenging task. STM imaging coupled with DFT calculations provides a powerful method for studying asymmetric induction on chirally modified catalysts. In combination, these techniques can be used to observe and define transient pre-organization complexes formed by binding the prochiral substrate to the chemisorbed chiral modifier. We present sub-molecularly resolved regiospecific and stereospecific data for isolated bimolecular and termolecular complexes formed at chiral sites on Pt(111). The measurements provide new insight on both the stereodirecting interactions involved and the dynamics of chiral selection.
