Synthesis, spectral, thermal, and a crystalline structure of complexes containing [MeC(CH_2PPh_2)_3Cu(I)]

摘要

The preparation of new [MeC(CH_2PPh_2)_3CuCl] 1 and its derivatives was carried out directly by mixing of CuCl and MeC(CH_2PPh_2)_3 ligand in dry THF, the neutral precursor 1 served to prepare [MeC(CH_2PPh_2) _3Cu(NCCH_3)]BF_4 2 and [MeC(CH _2PPh_2)_3Cu(PCH_2Ph) _3]BF_4 3. These complexes are characterized on the basis of elemental analysis, IR, EDS, ~1H, ~(13)C and ~(31)P{~1H}NMR, FAB-MS, TG/DTA and single-crystal X-ray diffraction studies. Complex 1 crystallizes in the Orthorhombic unit cells with the space group Pna2(1). The structural behavior of MeC(CH_2PPh _2)_3 ligand in the formed complexes during the coordination reaction was monitored by ~(31)P{~1H}NMR in CDCl_3 at room temperature for the first time.
