1293-65-8, 1,1′-Dibromoferrocene is a iron-catalyst compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,1293-65-8
1 ,1 ‘-Dibromoferrocene (0.67 g, 1.97 mmol) in anhydrous tetrahydrofuran (THF) (30 ml) was placed in a reaction vessel and cooled to -78 0C using a dry ice and acetone mixture, n-butyl lithium (0.94 ml, 2.36 mmol) was added under inert conditions thereto and the contents of the reaction vessel kept stirred for approximately 1 hour while cold zinc chloride (2.16 ml, 2.16 mmol) was added. Tetrakis(triphenylphosphine)palladiumO (50 mg) and 4-iodophthalonitrile (0.5 g, 1.97 mmol) were then added. The contents of the reaction vessel were allowed to warm to room temperature and were kept stirred for approximately 16 hours. Thereafter, water (20 ml) was added and extracted with dichloromethane (3 x 20 ml). The combined organic layers were dried over magnesium sulfate and reduced to dryness under reduced pressure to obtain a crude product. The crude product was placed on alumina and eluted with diethyl ether ; petroleum spirit (55:45) to yield red crystals.
1293-65-8 1,1’-Dibromoferrocene 72376387, airon-catalyst compound, is more and more widely used in various.
