WebThe bonding of a side-on co-ordinated π ligand to a transition metal fragment is usually described by the Dewar – Chatt – Duncanson model. 23 According to this model, the bonding arises from ... WebAug 2, 2001 · Both of these compounds have been structurally characterized, and the structural and spectroscopic data for these compounds support an η 2 bonding description for the borataalkene ligand which is reminiscent of the commonly held Dewar−Chatt−Duncanson model for alkene bonding to transition metals. WebJul 25, 2006 · Notably, for such trialkylsilyl-substituted 1,3-diynes, C−C coupling occurs exclusively at the carbon atom bearing silicon. π-Back-bonding from low valent rhodium as described by the Dewar−Chatt−Duncanson model appears to direct the regiochemistry of C−C coupling, as corroborated by calculations of the diyne LUMO coefficients. * dicks sporting goods gatorade water bottle
