General description
2-Methoxythiophene is a heterocyclic methyl enol ether and its reaction with o-quinone monoimide was studied. The intramolecular and intermolecular geometries of crystals of 2-methoxythiophene were investigated. Kinetics of the hydronium-ion catalysed hydrolysis of 2-methoxythiophene was reported.
Application
2-Methoxythiophene was used in thermal reaction (60°C) of (C5Me5)Rh(PMe3)(Ph)H.

The intramolecular and intermolecular geometries of six thiophenes carrying oxygen-containing substituents have been determined. Crystals of 2-methoxythiophene and 3-methoxythiophene were grown in situ on a diffractometer from liquid samples. The 2-methoxy group introduces significant distortions to the thiophene nucleus and
