2,5-disubstituted 1,3,4-oxadiazoles are a class of organic compound that are widely used and successful in pharmaceutical chemistry because they demonstrate strong biological activity. They are part of a larger class of compound called heterocycles, which make up most pharmaceutical drugs today. When synthesizing the compounds, higher yield means higher reactivity of the compound, and this is important for pharmaceuticals that need to have a strong biological activity. Per past studies, electron withdrawing groups on the compound allow higher, product yields. Along with electron withdrawing group addition, the bond length from electron withdrawing group and its corresponding carbon is analyzed to look for positive correlation between high product yield and electron withdrawing group addition. The objective of this research is clarified by two phases: synthesis of 1,3,4-oxadiazoles with different electron withdrawing groups and analysis of yield and bond length. The conclusion of these phases demonstrates a trend between bond length and yield of the para oxadiazoles. As product yield increases, the bond length of the electron withdrawing group to carbon shortens. This trend is not observed in the ortho products because of other unknown factors, including steric hindrances that may limit the strength of the electron withdrawing group.
