As a common heterocyclic compound, it belongs to iron-catalyst compound, name is Vinylferrocene, and cas is 1271-51-8, its synthesis route is as follows.

A mixture of vinylferrocene (1 mmol), K2CO3 (2.5or 5 mmol), tetrabutylammonium tetrafluoroborat (2.5 or 5 mmol),the given amount of appropriate bromine-substituted compoundand catalytic amount of Pd(OAC)2 in 10 ml DMF was stirred at 80 ¡ãCunder argon atmosphere overnight. After the completion of thereaction, the cooled mixture was filtered, diluted with CH2Cl2(50 ml) and washed with H2O (3 x 50 ml). The organic phase was dried over Na2SO4, filtered and the solvent was removed under thereduce pressure. The crude products were purified by columnchromatography on silica gel with hexane/EtOAC as eluent. Specificdetails for each compound are given below. 4-(2-Ferrocenylvinyl)benzaldehyde (3): from 0.1 g (0.47mmol)vinyl ferrocene and 0.08 g (0.47 mmol) 4-bromobenzaldehyde,0.11 g (0.36 mmol) red shining crystals was obtained in 88percent yield:Rf 0.50 (Hexane: EtOAc 9:1); m.p. 150 ¡ãC, lit. [13] 150-151 ¡ãC; 1HNMR (400 MHz, CDCl3, 25 C): delta 9.97 (s, 1H, CHO), 7.83 (d, 2H,ArH), 7.56 (d. 2H, ArH), 7.07 (d, 3J (H,H) 16 Hz, 1H, CH), 6.72 (d, 3J(H,H) 16 Hz, 1H, CH), 4.50 (t, J 1.78 Hz, 2H, Cp), 4.35 (t,J 1.78 Hz, 2H, Cp), 4.15 (s, 5H, Cp) ppm; FT-IR (KBr, cm1): 3074,3062 (w), 2936, 2852 (w), 1685 (s), 1591, 1561 (w), 814 (w).
