7650-91-1, Benzyldiphenylphosphine is a chiral-phosphine-ligands compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
7650-91-1, Pt(tht)2Cl2 (synthesized according to a method disclosed in J. Chem. Soc., Dalton Trans. 1980, 888-894; 100 mg, 1 eq, ?tht? represents tetrahydrothiophene), benzyldiphenylphosphine purchased from Alfa Aesar (68 mg, 1.1 eq), and sodium acetate (94 mg, 5 eq) were added in a 50 mL round-bottomed flask, and degassed xylene (purchased from ECHOChemical; Product no: XA2101-000000-72EC; 6 mL) was then added therein with mixing to obtain a mixture, followed by heating to 100 C. and reacting for 12 hours. The mixture was then cooled to room temperature, and a precursor solution (PS1) of a phosphorescent four-coordinated platinum (II) complex was obtained. 4-(2,6-diisopropylphenyl)-2-(3-trifluoromethyl-1H-pyrazol-5-yl)pyridine (84 mg, 1 eq) was added into the PS1 obtained from Synthesis Example 1 to obtain a mixture, and the mixture was heated to 100 C. and reacted for 6 hours, followed by cooling to room temperature and removing the solvent. Silica-gel column chromatography was conducted to purify the mixture using an eluent of dichloromethane and n-hexane (dichloromethane:n-hexane 1:1). Recrystallization was then conducted using dichloromethane/n-hexane so as to obtain a light yellow crystalline product, referred to as complex E6 (44.3% yield; 85 mg). The reaction scheme for producing the complex E6 is represented as follows: The spectrum analysis for the complex E6 is: 1H NMR (400 MHz, CDCl3, 298 K) delta 8.85 (d, J=8.3 Hz, 1H), 7.85-7.90 (m, 4H), 7.63 (d, J=5.7 Hz, 1H), 7.42-7.51 (m, 7H), 7.35 (t, J=7.8 Hz, 1H), 7.18 (d, J=7.8 Hz, 2H), 7.13-7.16 (m, 2H), 7.00 (t, J=7.4 Hz, 1H), 6.88 (s, 1H), 6.47 (dd, J=1.7, 5.7 Hz, 1H), 3.82 (d, J=11.4 Hz, 2H), 2.41 (hept, J=6.8 Hz, 2H), 1.10 (d, J=6.8 Hz, 6H), 0.99 (d, J=6.8 Hz, 6H), 19F NMR (400 MHz, CDCl3, 298 K) delta -60.7, 31P NMR (200 MHz, CDCl3, 298 K) delta 36.81, FAB-MS m/z 842.9 M+
As the paragraph descriping shows that 7650-91-1 is playing an increasingly important role.
