Bond cleavage reactions in substituted thiophenes by a rhodium complex

The reactions of (C(5)Me(5)) Rh(PMe(3))(Ph) H with 2-methoxythiophene, 3-methoxythiophene, 2-cyanothiophene, 3-cyanothiophene, 2-trimethylsilylthiophene, ethylenesulfide, trimethylenesulfide, and several polymethylthiophenes have been investigated. These thiophene derivatives give C-S and in one case C-H insertion products. Ethylene sulfide and trimethylene sulfide undergo ring opening or desulfurization. (C) 2007 Elsevier B.V.
