Derivatives Of

The derivatives of 3-ferrocenyl isocoumarin were synthesized by the condensation of substituted homothphalic anhydride with ferrocene using phosphoric acid or anhydrous aluminium chloride as cyclising agent. Substituted homophthalic acid did not condense with ferrocene so homophthalic acids were converted into their anhydride and then allowed to react with ferrocene in the presence of polyphosphoric acid or in the presence of anhydrous aluminium chloride using dichloromethane as the solvent to give 3-ferrocenyl isocoumarins. 7-Methoxy, 6-methyl, 5,7-dihydroxy, 6,7-dimethoxy and 5,7-dimethoxy derivatives of 3-ferrocenyl isocoumarin were synthesized. All the compounds were characterised by melting point determination, elemental and spectral analysis.

Alkylaromatic compounds such as alkylphenols are the most wide spread and efficient material due to its broad practical utilization in different arenas including antioxidants, stabilizers for fuels, lubricating oils, polymeric materials and so on. In this work, (2-phenylpropan-2-yl) m-cresol with high yield was prepared from the reaction between m-cresol and _-methylstyrene in the presence of anhydrous aluminium chloride catalyst. Plackett-Burman design was applied for screening significant variables, such as, temperature, molar ratio of m-cresol to _-methylstyrene, time of reaction and amount of catalyst etc. to determine an optimum condition for the production of (2-phenylpropan-2-yl) m-cresol. Moreover, a 23 Yates pattern factorial design was used to develop a mathematical model to predict the yield of alkylation of m-cresol with _-methylstyrene. Analyses of the results revealed that temperature, molar ratio and amount of catalyst were the main effective variables. The products were characterized by FT-IR, UV-visible and 1H NMR spectroscopy. The adequacy of the suggested model was checked up. The experimental yields exhibited good agreement with the predicted yields designed by the mathematical model. Hence, (2-phenylpropan-2-yl) m-cresol has the potential to be used as an industrially important compound in various applications. Bangladesh J. Sci. Ind. Res.54(3), 195-202, 2019

Polystyrene (PS) was synthesized by emulsion polymerization. The linear chloroacetylated PS was prepared high effectively by Friedel-Crafts acetylation of PS using chloroacetyl chloride and anhydrous aluminium chloride as chloroacetylation reagent and catalysts, respectively. The structure of chloroacetyl group is similar to that of chloromethyl group. In this method, carcinogenic compound (chloromethyl ether etc.) was avoided and the reactions of secondary cross link and multi-substitute could be eliminated. The resultant polymers were characterized by Fourier transform infrared spectrometery (FTIR) and thermogravimetric analysis. The effects of reaction conditions on chloroacetylation were studied, and the optimum reaction conditions were obtained. Chloroacetyl group was introduced into benzene ring of PS because of the appearance of the absorption peaks at 1695cm-1 (due to C=O bonds) and 644cm-1 (due to C-Cl bonds) in the FTIR spectrum. The thermal stability of the chloroacetylated PS was decreased with increasing chloroacetyl group. Moreover, there were two decomposing stages. The glass transition temperature of chloroacetylated PS increased with substitution value increasing. The effects of the reaction conditions such as reaction temperature, the solvent amount and the concentration of chloroacetyl chloride and anhydrous aluminium chloride on the chloroacetylation of PS were obvious. The certain loading can be controlled when it is lower than the maximum loading of chloroacetylated PS. The reaction condition is gentle and the operation is safe, simple and economical so that Friedel-Crafts acetylation of PS is an ideal reaction method.
