Pd-catalyzed synthesis of beta-biarylacryl ferrocenes via Suzuki cross-coupling

Some novel β-biarylacryl ferrocene derivatives were synthesized via Pd-catalytic Suzuki cross-coupling reactions of β-(2-bromophenyl)acrylferrocene and arylboronic acids. The structures were determined with elemental analyses, IR spectra, and 1 H-NMR spectra. Keywords: Pd-Catalyst; Biarenes; Ferrocenyl; Suzuki Cross- coupling Reaction. Introduction Over the last two decades, molecular-based second-order nonlinear optical (NLO) chromophores have attracted much interest because of their potential applications in emerging opto-electronic technologies [1-5]. These efforts have mainly focused on organic systems. More recently, organometallic molecules have been investigated as well [3-5]. In comparison to common organic molecules, they offer a large variety of novel structures. The possibility of high environmental stability and diversity of tunable electronic behaviors by virtue of the coordinated metal center might bring about NLO materials with unique characteristics such as magnetic and electro-chemical properties.
