2,5-Dimethoxythiophen, prepared from 2,5-di-iodothiophen, undergoes some electrophilic substitution reactions but is susceptible to ring opening by mineral acid. It is also decomposed by butyl-lithium. Reaction with maleic anhydride in xylene proceeds with extrusion of sulphur and a second Diels–Alder reaction to give a bis-adduct (2).
