Org. Chem., 58, 904 (1993). Conditions have been described for the formation of 3-lithiothiophene, previously considered to be stable only under cryogenic conditions. It has been found to be stable in hexane solution at ambient temperature: Tetrahedron Lett., 35, 3673 (1994). Subsequent reaction with electrophiles leads to a variety of 3-substituted thiophenes.
