| Abstract
| - The mechanism of the boron−zinc exchange reaction has been studied by applying densityfunctional calculations at the B3PW91 level of theory. It was found that the exchange reactionproceeds with a low activation barrier, involving two intermediates with unusual bondingstructures. The metal−carbon bonding in these intermediates ensures a highly stereoselectiveexchange process, which can be employed in asymmetric organometallic synthesis. On thebasis of the theoretical results we predict that organogallium and organoindium compoundscan also be generated by alkyl exchange reactions from organoboranes.
