General procedure: The general procedure for the synthesis and characterization of 1,1?-ferrocenyl-diacrylonitriles is displayed in Scheme 1 and has been previously reported [20]. In brief, 1,1?-ferrocenedicarboxaldehyde and substituted phenylacetonitriles (2.2 Eq.) were mixed in a Pyrex tube fitted with a ground glass joint. The compounds were thoroughly ground in the open air with a glass rod in the presence of 1-2 drops of piperidine to form a melt. The melt was first dried in open air, followed by drying under a vacuum line. The dry products were purified by means of silica gel chromatography. Formation of the products was determined by use of IR or NMR spectroscopy (1H- and 13C-NMR). In the solid-state IR spectra, the formation of the products was characterized by the disappearance of the sharp carbonyl absorption band at approximately 1650cm-1 and the appearance of a strong nitrile absorption band at approximately 2200cm-1. The 1H- and 13C-NMR spectra showed the disappearance of the carbonyl resonance (?10ppm) and the appearance of alkene resonance peaks (?7.4ppm). Pure compounds were further analyzed by melting point determination (DSC), mass spectrometry, microanalysis, and X-ray diffraction. 4.2.1 1,1?-Ferrocenyldi[-2(4-cyanophenyl)acrylonitrile] (para-CN catalyst) The general procedure for the synthesis of this catalyst is described in Section 4.2 and involves the use of 1,1?-ferrocenyldicarboxaldehyde (145.0 mg, 0.60 mmol) and 4-cyanophenylacetonitrile (188.0 mg, 1.32 mmol). Upon grinding, a deep maroon paste was formed which was dried to obtain a maroon solid. Reaction completion was monitored by use of preparative TLC plates with a solvent system of hexane/diethyl ether (1:1). The final product was then purified by means of column chromatography with a solvent system of hexane/diethyl ether (1:1) to obtain dark maroon crystals (219.0 mg, 74%) as the desired product and 37.0 mg of the recovered starting (1,1?-ferrocenedicarboxaldehyde).
