As a common heterocyclic compound, it belongs to iron-catalyst compound, name is 1,1′-Dibromoferrocene, and cas is 1293-65-8, its synthesis route is as follows.,1293-65-8
Part ( I)Preparation of 1-bromo-l’ -trimethylsilyl ferroceneTo 1, 1 ‘-dibromoferrocene (1Og, 29.08mmol) in dry THF (200ml) cooled to -780C (dry ice/acetone bath) was added n-butyllithium (11.05ml, 27.63mmol, 0.95eq) and the reaction was stirred under N2 for 30 min. Chlorotrimethylsilane (3.7ml, 29.08mmol, leq) was then added dropwise and the solution was then allowed to warm up to room temperature and further stirred for twelve hours resulting in a red solution.The reaction was then quenched with water, and stirred for a further fifteen minutes. The ethereal layer, containing product was separated and the aqueous layer was further extracted several times with diethyl ether. The combined ether fractions were dried over magnesium sulphate and filtered through celite. The ether solvent was removed by rotary evaporator (resulting in red oil) . The product was purified as the initial red band (petrol) by column chromatography. The resulting red oil was finally dried under vacuum: (7.11g, 73 % yield) .
With the complex challenges of chemical substances, we look forward to future research findings about 1293-65-8,belong iron-catalyst compound
