                                    A systematic study on hippuric acid substituents was performed in order to better understand the influence of stereoelectronic factors on the Erlenmeyer reaction rate. In addition, two reaction systems were evaluated: Hunig's base solvent free conditions and catalytic sodium acetate in 2-methyl-THF. The effect on reaction rate of electron withdrawing and electron donating groups are reported. Specifically, the study led to the conclusion that stereoelectronic factors have significant influence in one of our key Erlenmeyer reaction by affecting its reaction rate.
