13991-08-7, 1,2-Bis(diphenylphosphino)benzene is a chiral-phosphine-ligands compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

1,2-Bis(diphenylphosphino)benzene (DPPBz) ligand (0.405g, 0.907mmol) was dissolved in a minimal amount of THF (no more than 7mL) in a glovebox at room temperature with stirring in a 25mL round bottom flask fitted with a rubber septum. Then 0.2mL (0.0907mmol) of Fe(CO)2(NO)2/THF solution (1:1 ratio) was introduced into the flask via syringe. The solution was allowed to stir at room temperature overnight to produce the monosubstituted product, Fe(NO)2(CO)(DPPBz). After stirring, the reaction mixture was taken out of the glovebox and gently heated at 50C for 24h with the reaction progress monitored through FT-IR spectroscopy. The solution was transferred back into the glovebox after completion of the double substitution. Large dark purple crystals of X-ray quality ranging in size from 0.5 to 3mm3were grown by allowing the solvent to slowly evaporate over several days through a vent needle. The crystals and solid powder from the bottom of the flask were filtered and washed with three 0.5mL aliquots of cool toluene.

7650-91-1, To a white suspension of P(CH2C6H5)Ph2 (2.08 g, 7.53 mmol) in toluene (20 mL) in a 300 mL Kjeldahl flask, added dropwise a yellow solution of 3c (1.83 g, 7.17 mmol) in toluene (20 mL) at 25 oC. The combined mixture became a clear yellow solution immediately. After stirring for 15 minutes effervescence was observed. The solution was stirred for 4 hours and it remained a clear yellow solution. Removal of the solvent under vacuum afforded a yellow viscous material which was redissolved with CH2Cl2 (20 mL). The resulting clear yellow solution was transferred via cannula over to a suspension of [PyH][BF4] (1.29 g, 7.17 mmol) in CH2Cl2 (20 mL). The Kjeldahl flask was rinsed with CH2Cl2 (2×20 mL) and the rinsing solution was transferred to the reaction flask via cannula. Pyridine (0.9 mL, 10.8 mmol) was added to the white suspension in CH2Cl2 and the reaction mixture was refluxed for 12 hours. After cooling the reaction to 25 oC, a clear yellow solution was observed and the volatiles were removed under vacuum. The resulting viscous residue was washed with diethyl ether (4 x 40 mL) to give a yellow gum. The gum was purified by column chromatography using silica gel (80 g) and CH2Cl2. The column was eluted with CH2Cl2 (200 mL), CH2Cl2-MeOH 98:2 (500 mL), CH2Cl2-MeOH 95:5 (500 mL), CH2Cl2-MeOH 90:10 (500 mL), and CH2Cl2-MeOH 80:20 (500 mL). The fractions (100 mL) were analyzed by UV-Vis, and those that contained the product were combined and dried under vacuum, affording white foam. The foam was treated with CH2Cl2 (100 mL) and diethyl ether (300 mL) to afford a white precipitate. Filtration of the precipitate followed by diethyl ether washes (40 mL) afforded 17 (2.17g, 66%) as a white powder. 1H NMR ((CD3)2SO): delta 9.66 (d, JPH = 10.4, 1H, -P=NH-), 7.97 (m, 4H, 2,6-CH of -(C6H5)2P=NH-), 7.82 (m, 2H, 4-CH of -(C6H5)2P=NH-), 7.70 (m, 4H, 3,5-CH of -(C6H5)2P=NH-), 7.54 (s, 1H, -CH of C6H3SO3), 7.20-7.28 (m, 3H, 2,6- and 4-CH of -C6H5CH2P=NH-), 7.10 (m, 3,5-CH of -C6H5CH2P=NH-), 6.91 (dd, J = 8.0, 1.6, 1H, 4-CH of -C6H3SO3-), 6.64 (d, J = 8.0, 1H, 3-CH of -C6H3SO3-), 5.00 (d, JPH = 14.0, -CH2P=NH-), 2.21 (s, 3H, 5-CH3 of -C6H3SO3-). 1H NMR (CD2Cl2): delta 9.68 (d, JPH = 10.4, 1H, -P=NH-), 7.71-7.85 (m, 7H, 6-CH of -C6H3SO3-, 3,5-CH of -(C6H5)2P=NH-, and 2,6-CH of -C6H5CH2P=NH-), 7.62 (, m, 4H, 2,6-CH of -C6H5CH2P=NH ), 7.28 (m, 1H, 4-CH of -C6H5CH2P=NH), 7.20 (t, J = 7.6, 3,5-CH of -C6H5CH2P=NH-), 6.96 (m, 2H, 4-CH of -(C6H5)2P=NH-), 6.79 (dd, J = 8.4, 2.0, 1H, 4-CH of -C6H3SO3-), 6.34 (d, J = 8.4, 1H, 3-CH of -C6H3SO3-), 4.27 (d, JPH = 14.0, -CH2P=NH-), 2.23 (s, 3H, 5-CH3 of -C6H3SO3-). 31P NMR ((CD3)2SO): delta 35.9. 31P NMR (CD2Cl2): delta 36.1. 13C NMR ((CD3)2SO): delta 137.0 (d, JPC = 7.8), 135.6 (d, JPC = 3.1, para-CH of -(C6H5)2P=NH-), 133.1 (d, JPC = 10.8, ortho-CH of -(C6H5)2P=NH-), 132.7, 132.4, 131.1, 131.0 (d, JPC = 3.1), 130.4 (d, , JPC = 10.8, meta-CH of -(C6H5)2P=NH-), 129.3 (d, JPC = 3.1), 128.5, 128.4, 128.0 (d, JPC = 10.0, ipso C of -C6H5CH2P=NH-), 120.5 (d, JPC = 96.8, ipso C of -(C6H5)2P=NH-), 119.5 (d, JPC = 3.9), 30.9 (d, JPC = 56.5, -CH2P=NH-), 20.5.

General procedure: PR3 and NH4PF6 were added to a solution of fac-[RuCl3(NO)(P?N)] (1) in MeOH (5 mL) and the resulting orange suspensionwas refluxed for 3 h, except for the P(p-Me-C6H4)3 system whenreaction occurred at r.t. After being cooled to room temperature,the resulting yellow suspensions of complexes 3?5 were filteredto give a yellow solid that was washed with H2O (2 5 mL), MeOH(2 5 mL) and Et2O (2 5 mL), and then dried in vacuo. In the caseof complex 2, the reaction generated a clear yellow solution; thesolvent was removed in vacuo to give a yellow residue that wasthen largely dissolved in CH2Cl2 (5 mL), and the mixture wasfiltered through Celite. Addition of n-hexane (15 mL) yielded a yellowsolid that was then treated as described above. The mer, transisomerof 1 [6,7] could also be used as the precursor for synthesesusing the same methodology, which gave similar product yields., 18437-78-0
