Group 11 Borataalkene Complexes: Models for Alkene Activation.

ABSTRACT: A series of linear late transition metal (M=Cu, Ag, Au and Zn) complexes featuring a side-on [B=C]^- containing ligand have been isolated and characterised. The [B=C]^- moiety is isoelectronic with the C=C system of an alkene. Comparison across the series shows that in the solid-state, deviation between the η² and η¹ coordination mode occurs. A related zinc complex containing two [B=C]^- ligands was prepared as a further point of comparison for the η¹ coordination mode. The bonding in these new complexes has been interrogated by computational techniques (QTAIM, NBO, ETS-NOCV) and rationalised in terms of the Dewar-Chatt-Duncanson model. The combined structural and computational data provide unique insight into catalytically rel
