The reaction of <I>o</I>- and <I>p</I>-anisaldehyde with potassium ethylthioxide in diglyme at 90–120 °C gave the corresponding demethylated products, while 2,6-dimethoxy-benzaldehyde and 9-(2-<I>p</I>-cymenyl)-2-methoxy-1-anthralde-hyde afforded two novel condensation and substitution products, VII and VI respectively.
