Synthesis and characterization of Cu(I) chelate complexes with 1,3-bis(diphenylphosphino)propane, 1,2-bis(diphenylphosphino)benzene and perfluorinated carboxylates
摘要:
Cu(I) complexes with 1,3-bis(diphenylphosphino)propane (dppp), 1,2-bis(diphenylphosphino)benzene (dppB) and perfluorinated carboxylates of the general formula [Cu(diphosphine)(2)](RCOO), R = C2F5, C4F9, C6F13, C8F17, C9F19, have been prepared and characterized with MS, IR and H-1, P-31, C-13, F-19, Cu-63 NMR spectroscopy. The presence of distinct bis-chelated cations of [Cu(diphosphine)(2)](+) type and uncoordinated carboxylate anions has been proposed. (C) 2003 Elsevier Ltd. All rights reserved.
