While we have focused on anthraquinone and benzoquinone derivatives in DMSO, the methods employed here can be readily extended to other redox active molecules including other types of quinones,, sulphides, and other redox active molecules. Effects of other aprotic solvents can be easily extended with the current method using implicit solvation models while those of ionic liquids in recent developments are likely to call for combination with more expensive hybrid quantum mechanics/molecular mechanics approach.
