Green chemistry principles were applied to multi-step synthesis reactions; these reactions included the bromination of trans-diphenylethylene, bromination of ethyl trans-cinnamate, and debromination of 1, 2-dibromo-1, 2-diphenylethane. These reactions featured a reflux set-up, which allowed the reactions to occur at higher temperatures and aided in the prevention of the evaporation of the solvent and the loss of product thereby increasing the efficiency of the reactions. Furthermore, the reactions were conducted in accordance to the principles of green chemistry. These principles are utilized to design synthesis processes which minimize the production of malignant compounds that can cause accidents in the laboratory.1 The products collected for each reaction were analyzed via melting point, TLC, NMR, GC-MS, and IR analysis in order to assess the purity and identity of the compounds synthesized. Green chemistry calculations for percent recovery, atom economy, and E product were utilized to determine the efficiency of the bromination and debromination reactions. Through such, the sustainability of these mechanisms, when green chemistry principles were applied, could be determined.
In an undergraduate laboratory setting, it is crucial to be familiar with and practice green chemistry principles in order to be able to apply these concepts to future organic chemistry experimental procedures. The twelve principle of green chemistry strive to reduce or completely eliminate the…
