摘要：
Changing behavior: A nucleophilic sp2 carbene-type boryl moiety, formed upon interaction of tetraalkoxydiboranes and a Lewis base, can attack non-activated C=C bonds. Computational studies identify the interaction as the overlap between the strongly polarized B-B σ bond (HOMO) and the antibonding πorbital (LUMO) of the C=C bond. Conceptually, the normally electrophilic boron becomes nucleophilic and forces the olefin to act as an electrophile. Copyright © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
