3-, 4-, and 5-dimethylsulfonio derivatives of salicylaldehyde have been prepared from the corresponding 6-, 5-, and 4-bromo-2-methylanisoles via the bromo-2-methoxybenzylidene dibromides, bromo-o-anisaldehyde diethyl acetals, methylthio-o-anisaldehydes, and (methylthio)salicylaldehydes. 4-Methylthio-o-anisaldehyde has also been prepared from 2-bromo-5-(methylthio)anisole.
