Synthesis, crystal structure and DFT calculations on 2,6-diisopropylphenylcopper; its use in the preparation of dichloro-2,6-diisopropylphenylphosphine

Abstract:

The homoleptic aryl copper reagent [Cu(4)Dipp(4)] (Dipp=2,6-diisopropylphenyl) has been prepared and structurally characterized by a single-crystal X-ray diffraction study. Its tetrameric structure differs in significant details from that of the previously reported [Cu(4)Tripp(4)] (Tripp=2,4,6-triisopropylphenyl). The electronic structure of the cluster has been probed through B3LYP/6311G(2d,p)//B3LYP/6-31G calculations on [Cu4Ph4] constrained to D-2d symmetry. The utility of the new copper reagent is demonstrated by the preparation of pure DippPCl(2), for which the crystal structure is also reported. (c) 2006 Elsevier B.V. All rights reserved.
