The parent 2hW-thien0[3,4-c]thiophene was generated by Pummerer dehydration of 1 H,3H-thieno[3,4-c]thiophene 2-oxide and characterized by chemical trapping experiments. ... The chemistry of 2h462-thieno[3,4-c]thiophenes (so-called 'non-classical' thienothiophenes) has been attracting consider- able attention.'--3 Although no report has appeared on the preparation of the parent thieno[3,4-c]thiophene (l), several derivatives of (1) -have
