Name is Vinylferrocene, as a common heterocyclic compound, it belongs to iron-catalyst compound, and cas is 1271-51-8, its synthesis route is as follows.,1271-51-8
General procedure: In an Schlenk tube under argon one of the following central coresC1, or C2 was mixed with 5percent palladium (II) acetate, Pd(OAc)2, 10percentTris(o-tolyl)phosphine, P(o-tol)3, and vinyl ferrocene, 1-Fc, in triethylamine/THF, 15 mL/15 mL. The resulting mixture was stirred and refluxedovernight. After removing the solvent under reduced pressure,the oil obtained was washed with distillated water and extracted inCH2Cl2 three times and dried over MgSO4. The extract was concentratedto dryness and purified by column chromatography (silica gel60) using hexane/CH2Cl2 2:1 (V/V) mixtures as eluent. The correspondingcompounds were isolated after removing the solvent in a rotaryevaporator. Compound 1. 1-Fc (187 mg, 8.84 mmol), C1 (150 mg,0.253 mmol), Pd(OAc)2 (2.8 mg, 0.0126 mmol), P(o-tol)3 (7.7 mg,0.0253 mmol), triethylamine/THF, 15 mL/15 mL. Yield 49.5percent.

MP: 199 ¡ãC – 200 ¡ãC.
With the complex challenges of chemical substances, we look forward to future research findings about Vinylferrocene
