Source of material

To a nitrogen saturated Schlenk tube, dichloromethane (30 mL, dry) together with cyclohexylamine (5.6 mmol, 0.65 mL) were added. This was followed by the drop-wise addition of triethylamine (7.5 mL). Thereafter, chlorodiphenylphosphine (5.6 mmol, 1.0 mL) was added drop-wise to the amine solution held at −78 °C. The solution was allowed to stir for 30 min, after which a second aliquot of chlorodiphenylphosphine (5.6 mmol, 1.0 mL) was added drop-wise. The mixture was allowed to reach room temperature and was stirred for approximately 14 h. The solution was filtered via cannula for the removal of the triethylammonium hydrochloride salt. Diethyl ether was added to the filtrate for further precipitation of the salt. The product was isolated after filtering twice through a short column packed with neutral alumina. The column was extracted with diethyl ether. The solvent was removed under reduced pressure and product was allowed to dry overnight under vacuum. Yield: 53%; 1.38 g (white powder), M.p.: 132.7–134.8 °C, 1H NMR (400 MHz, CDCl3) δ: 0.99–1.05 (quintetJ = 11.92 Hz, 2H), 1.32–1.46 (br d, 2H), 1.53–1.60 (br m, 4H), 1.82–1.88 (q, J = 12.38 Hz, 2H), 3.18–3.25 (m, 1H), 7.24–7.39 (br m, 17H). Colourless crystals were grown by slow evaporation from dicholoromethane at room temperature.

Experimental details

Cell refinement and data reduction were performed using the program SAINT [25]. The data were scaled and absorption correction performed using SADABS [25]. The program OLEX2 used to prepare molecular graphic images [27]. All hydrogen atoms were placed in idealised positions and refined in riding models with Uiso assigned 1.2 times Ueq of their parent atoms and the bond distances were constrained to 0.95 Å for aromatic hydrogens and 0.99 Å for CH2.

Discussion

PNP-pincer, a tridentate ligand, is reported as being a strong binding metal ligand, which allows for the stabilization of homogenous catalyst complexes even at high reaction temperatures. The modular structure of the ligands enables “tuning” of the catalyst activity and selectivity through systematic variation of the donor atoms, their substituents, and the ligand backbone framework. There are numerous examples of crystal structures of such PNP-pincer ligands [16] and metal complexes [724]. Diphosphinoamine (PNP) and other P donor ligands [721] with various substituents on both the P and N atoms have been applied to several catalytic reactions such as methoxycarbonylation [17], metathesis [18], hydroformylation [19] and C—H activation [24].

Here we report for the first time the crystal structure of the title compound (Figure) as part of our ongoing C—H activation project. The PNP moieties are aligned via C—H⋯π weak interactions and create a stair structure. Molecules that are packed in parallel glide via π⋯π interactions form sheets across the (101) plane. The presence of C—H⋯P and C—H⋯π weak interactions link the cyclohexyl ring in a chair conformation with the phosphorous atom.
