Quinones. Part 10. Side-chain Methylthiolation of Methylbenzoquinones

2,3,5,6-Tetramethylbenzoquinone undergoes side-chain reaction with excess of sodium methanethiolate to form mono-, di-, and tri-methylthiomethyl derivatives in low yields. 2,5- and 2,6-Dimethylbenzoquinones react first on the nucleus to give dimethyl(dimethylthio)quinones followed by limited side-chain methylthiolation.The side-chain reaction is restricted by a competing redox reaction.The presence of semiquinone radical anions can be detected by selective line-broadening in the n.m.r. spectra of quinone-thiolate solutions.
