Oxidative Addition of Phenylacetylene through C-H Bond Cleavage To Form the Mg~II-dpp-bian Complex:Molecular Structure of [Mg{dpp-bian(H)}(C ident to CPh)(thf)_2] and Its Diphenylketone Insertion Product [Mg(dpp-bian)~centre dot - {OC(Ph_2)C ident do

摘要

Over the past decade dpp-bian began to be used widely in coordination chemistry owing to anumber of interesting chemical reactions,which include catalytic olefin polymerization,~[1] shown by the metal complexes based on this ligand.~[2]The rigidity and bulkiness of the ligand and its pi-acceptor propertis cause an electron deficiency at the coordinated metal and render these complxes highly reactive towards organic substrates.
