With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.13689-19-5,Tricyclohexylphosphine oxide,as a common compound, the synthetic route is as follows.

General procedure: The same general procedure was adopted for the synthesis of all the complexes. The lanthanide bromide and tricyclohexylphosphineoxide were dissolved in hot ethanol. Heating was continued for 1 h during which time, in some cases, small quantities of crystalline material formed. Either cooling to room temperature followed by standing for 16 h or on prolonged standing and slow evaporation of the solution afforded crystalline materials. The crystals were filtered, washed with ethanol and dried at the pump. Representative syntheses and characterisations are described below.

General procedure: In a sealed tube containing a solution of the phosphine oxide derivative (5 mmol) in anhydrous toluene (1 M) was added InBr3 (1 mol %, 0.05 mmol) and the TMDS (1.5 equiv, 7.5 mmol) under an argon atmosphere. The reaction mixture was stirred at 100 C during 7-40 h depending on the substrate (the reaction was monitored by 31P NMR). After complete consumption of the reagent the mixture was kept under argon in the sealed tube and cooled to 0 C. A solution of BH3.SMe2 (2 M in THF, 1 equiv) was then slowly added. After 1 h at room temperature, 31P NMR analysis of an aliquot indicates complete conversion to phosphine borane adduct. The crude was poured in an erlenmeyer flask and silica gel was carefully added while stirring. When silica gel was added in the reaction mixture, a slightly exothermic reaction was observed. The reaction mixture was then filtered on silica gel and washed several times with ethyl acetate. After evaporation of the ethyl acetate, the residue was purified by flash chromatography on silica gel with pure cyclohexane to afford the desired phosphine-borane.

Ce(NO3)4(Cy3PO)2 An excess of CAN (0.45 g 0.82 mmol) in2.5 mL water were stirred with a solution of Cy3PO (0.24 g0.81 mmol) in 1.8 mL of chloroform for 10 minutes. The orangechloroform layer was separated, dried (MgSO4), filtered and mixedwith an equal volume of diethylether. Cooling to -30 C gave yellowneedles suitable for X-ray crystallography (0.19 g 46% based onCy3PO). Analysis (%) Expected (found): C 44.08 (44.92) H6.78 (6.73)N 5.71 (5.69).

General procedure: NMR titration experiments of the guests HPCy3+, N-tosyldiallylamine (7) and Cy3P=O withsulfocalixarenes 1 as hosts: The titration experiments were performed at least in duplicate using a standard?constant guest? method in 600-640 muL D2O with addition of 7-10 muL MeOD-d4 or 10 muL DMSO-d6as internal standard (deltaH (MeOD-d4) = 3.31 ppm; deltaH (DMSO-d6) = 2.50 ppm) at room temperature. AllH-atoms of the guests HPCy3+, N-tosyldiallylamine (7) and Cy3P=O were evaluated using MestRe-C [32]and MestReNova [33]. Kass and log K values of the receptors were obtained by analysising the course ofthe chemical shifts of the protons of the guest HPCy3+, N-tosyldiallylamine (7) and Cy3P=O using theprogram HypNMR2008 [34,35].
