ABSTRACT
Methods of selectively synthesizing diorganyl diselenides (R-Se-Se-R) without using harmful reducing agents are presented. We optimized the reaction conditions for the selective formation of the diselenide dianion (Se22-) and the corresponding diorganyl diselenides using basic reagents (e.g., KOH), while suppressing the formation of side products, such as diorganyl selenides (R-Se-R) or multiselenides (R-Sen-R; n ≥ 3). Furthermore, we have suggested and examined the reaction pathways responsible for the formation of the desired diorganyl diselenides 1 and side products 2 and 3. Consequently, the selective synthesis of diverse diorganyl diselenides was achieved with modest to excellent yields (33-99%) using various organyl halides under optimized conditions. The results provide a practical and efficient synthetic method for diorganyl diselenides as a representative class of organoselenium compounds.
