Insertion reactions of organic anhydrides and the Cu(I) alkoxide [(CuOBu)-Bu-t]

摘要

The synthesis and structural characterization of the copper salts [Cu-8(benzoate)(8)(THF)(6)] (1), [Cu-2{(CO2)(2)C6H2(Boc)(2)}dppm(2)](2) (2) and [Cu-2{(CO2)(2)C10H4(Boc)(2)}dppm(2)](2) (3) [Boc = tert-butoxycarbonyl, dppm = 1,2-bis(diphenylphosphino)methane] prove that cyclic organic anhydrides and dianhydrides readily insert into the Cu-O bond of [CuO'Bu] forming carboxylate ligands with ester functionalities in the ligand periphery. [Mn-3(o-Boc-benzoate)(6)(DME)(2)] (4) (DME = 1,2-dimethoxyethane) was synthesized by the metathesis reaction of [Cu(I)(o-Boc-benzoate)] with MnCl2. (c) 2005 Elsevier B.V. All rights reserved.
