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
An oven dried 200 mL two-necked flask equipped with a magnetic stirring bar and a reflux condenser was charged with a solution of anhydrous lion (II) bromide (1.5 g, 6.95 mmol) and 1,2-bis (diphenylphosphino) benzene (3.41 g, 7.65 mmol) in ethanol (70 mL). The reaction flask was heated to 80 C for 18 hours, at this time pale brown colored precipitate was formed. The reaction mixture was cooled to room temperature. Filtered the brown solid and was washed with 100 mL of hot ethanol. The resulting yellowish brown solid 5a (3.54 g, 77%) was dried under high vacuum for 12 hours.
13991-08-7, As the paragraph descriping shows that 13991-08-7 is playing an increasingly important role.
