Title: Butyl 2-Cyano-(3,5 dichloro-phenyl)-2-propenoate
Abstract: The targeted trisubstituted ethylene compound Butyl 2-Cyano-(3,5 dichloro-phenyl)-2-propenoate and its copolymer with styrene was prepared in this lab. The base catalyzed Knoevengael condensation of butyl cyanoacetate and corresponding aldehyde led to the forming Butyl 2-Cyano-(3,5 dichloro-phenyl)-2-propenoate. The analyses that were used to prove its composition and structure include; IR spectroscopy, thin layer chromatography (TLC), and CHN analysis. A radical copolymerization reaction was conducted, with the initiation by radical initiator 1,1’-azobiscyclohexanecarbonitrile. CHN analysis, IR spectroscopy, and Proton NMR analysis were used to prove its composition and structure.
1. Introduction
The American Chemical Society databases were investigated through Scifinder Scholar Version X to find any information about Butyl 2-Cyano-(3,5 dichloro-phenyl)-2-propenoate. There was no previous information present. Then, the microscale synthesis and characterization of Butyl 2-Cyano-(3,5 dichloro-phenyl)-2-propenoate was conducted with the base catalyzed Knoevengael condensation of the butyl cyanoacetate and corresponding aldehyde (gkharas/235_14F/235_14F_Lab_2.pdf) and analysis. The elemental analysis that was conducted through CHNX analysis, determined the actual composition of the Butyl 2-Cyano-(3,5 dichloro-phenyl)-2-propenoate that had been synthesised. A typical radical copolymerization reaction was then conducted, with the initiation by the radical initiator 1,1’-azobiscyclohexanecarbonitrile (ABCN). Then, the copolymer isolation procedure allowed the final product to be analyzed by IR, and provided ample evidence that determined that Butyl 2-Cyano-(3,5 dichloro-phenyl)-2-propenoate been successfully synthesized.
