Resumen
The autoxidation of benzoin, commonly used as a demonstration experiment, has attracted interest from some chemical educators. Traditionally, this process is utilized to showcase the transformation of benzoin into benzil via a visible color change. However, the formation of multiple oxidation products beyond benzil is an often-overlooked phenomenon. By integrating macroscopic observation with molecular-level analysis, a revised approach allows students to investigate the potential oxidation mechanisms. Benzil is not the primary product; therefore, the conventional experimental method is inadequate for its direct preparation. Gaining insight into the underlying mechanisms could optimize the autoxidation of benzoin, rendering it potentially valuable for laboratory synthesis. Herein, a room-temperature synthesis method for benzil has been developed, which is specifically designed for use in educational laboratory settings.
