In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Synthesis and solid-state characterization of platinum complexes with hexadentate amino- and iminophosphine ligands, published in 2009-10-07, which mentions a compound: 12266-72-7, mainly applied to phosphinophenylaminocyclohexane preparation coordination platinum; hexadentate amino imino phosphine ligand preparation coordination platinum; crystal mol structure phosphinophenylaminocyclohexane phosphinophenyliminocyclohexane platinum complex, Application In Synthesis of Diiodo(1,5-cyclooctadiene)platinum(II).
Hexadentate ligands cis,cis-C6H9(N:CHC6H4(PPh2))3 (1) and cis,cis-C6H9(NHCH2C6H4(PPh2))3 (2) were synthesized starting from cis,cis-1,3,5-triaminocyclohexane, and characterized using NMR spectroscopy and single-crystal x-ray diffraction. These ligands can bind both Pt(0) and Pt(II) metal centers using either or both of the soft phosphine moieties and the hard amine/imine moieties. In many cases the resulting complexes are negligibly soluble; hence, 31P and 195Pt solid-state NMR (SSNMR) spectroscopy was applied to analyze the bonding modes of the hexadentate ligands. The 195Pt SSNMR spectroscopy of these complexes is particularly challenging, since 1H-195Pt cross polarization is extremely inefficient, the 195Pt longitudinal relaxation times are extremely long and the 195Pt powder patterns are expected to be quite broad due to platinum chem. shift anisotropy. It is demonstrated that the ultra-wideline 195Pt SSNMR spectra can be efficiently acquired with a combination of frequency-stepped piecewise acquisitions and cross-polarization/Carr-Purcell Meiboom-Gill (CP/CPMG) NMR experiments The 195Pt and 31P SSNMR data are correlated to important structural features in both Pt(0) and Pt(II) species.
In addition to the literature in the link below, there is a lot of literature about this compound(Diiodo(1,5-cyclooctadiene)platinum(II))Application In Synthesis of Diiodo(1,5-cyclooctadiene)platinum(II), illustrating the importance and wide applicability of this compound(12266-72-7).
