title: Palladium-catalyzed benzothieno[2,3-b]indole formation via dehydrative-dehydrogenative double C-H sulfuration using sulfur powder, indoles and cyclohexanones.
abstract: Palladium-catalyzed C-S bond formation via dehydrative-dehydrogenative double C-H sulfuration using sulfur powder is described. The dehydrogenated intermediates of cyclohexanones can be trapped to act as efficient aryl sources under an oxygen atmosphere. This procedure provides a novel approach for the preparation of benzothieno[2,3-b]indoles.
