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.
13991-08-7, 13991-08-7 1,2-Bis(diphenylphosphino)benzene 498379, achiral-phosphine-ligands compound, is more and more widely used in various fields.
