Vinylferrocene, cas is 1271-51-8, it is a common heterocyclic compound, the iron-catalyst compound, its synthesis route is as follows.,1271-51-8
Under argon, into a dried reactor were added successively vinyl ferrocene (1mol, 212g), (R ) -3,3′-bis (3,5-dimethylphenyl) -1,1 ‘ – binaphthol phosphonate (0.01mol, 5.6g) and 1L of toluene, followed by addition of di-tert-butylphosphine (1mol, 147g), heated to 60 deg.] C for 12 hours, then cooled cooling, water was added dropwise to the system, and then liquid separation, the organic layer was dried over anhydrous magnesium sulfate, filtered, and the solvent evaporated under reduced pressure to give a yellow solid which was recrystallized from dichloromethane and methanol to give (R) -1- ferrocenyl ethyl-di-tert-butylphosphine 347g yield 97percent, ee value of 99.5percent.
With the rapid development of chemical substances, we look forward to future research findings about 1271-51-8
