“…145 Arylsulfonamide chalcones are compounds that satisfy these criteria, with a synthesis in ≤5 steps with solubility in polar and non-polar solvents and with high purity. 146,147 In addition, it is important to consider (1) the cost, (2) availability, (3) sustainability, and (4) the potential formation of nitrogen and sulfur oxides during combustion. Although arylsulfonamide chalcones have some challenges, further research on chalcone-based compounds will inform the applicability of chalcones as biofuel additives, as well as their comparison with existing antioxidants.…”
