Treatment of 1-diazo-3-(2-thienyl)-2-propanone with catalytic rhodium (II) acetate results in cyclopropanation followed by acid-catalyzed ring opening and tautomerization to yield 5,6-dihydro-4Hcyclopenta[b]thiophen-5-one. Under the same conditions, however, the isomeric l-diazo-3-(3-thienyl)-2propa
