| Abstract
| - The rhodium-catalyzed reaction between bis(catecholato)diboron and simple alkenes results in thesyn addition of the diboron across the alkene. The resulting 1,2-bis(boronate) is subsequentlyoxidized to provide the 1,2-diol. In the presence of enantiomerically enriched Quinap ligand, highenantioselection in the diboration can be achieved. The reaction is highly selective for trans- andtrisubstituted alkenes and can be selective for some monosubstituted alkenes as well. Thedevelopment of this reaction is described as is the substrate scope and experiments that areinformative about the reaction mechanism and competing pathways.
