Systhesis of β-Biarylacrylferrocene by Suzuki-Miyaura Cross-coupling Reaction

【摘要】:正The catalytic cross-coupling reaction of β-(2-bromophenyl)acrylfrerrocene and β-(4-bromophenyl)-acryl-frerrocene (1) with arylboronic acid (2) to prepare biaryl analogues, permits the extension of molecular conjugation. β-(2-Bromophenyl)-acrylfrerrocene and β-(4-bromophenyl)acrylfrerrocene (1) were transformed in β-biarylacryl-ferrocene (3) by Suzuki cross-coupling reaction with arylboronic acid (2) in the presence of Pd?in a sodium carbonate solution of water. The new compounds were separated in good yield by column chromatography with petroleum ether/acetate from 20: 1 to 4: 1 (V: V) as eluants.
