Palladium-catalyzed Heck reactions of brominated thiophenes, N-methylimidazole, N-methylpyrrole and N-methylindole are also presented. The products were transformed by subsequent 6π-electrocyclization and dehydrogenation to functionalized benzothiophenes, dibenzothiophenes, benzimidazoles, indoles and carbazoles, respectively. palladium Suzuki reaction Heck reaction electrocyclizations heterocycles Universitätsbibliothek Rostock http://purl.uni-rostock.de/rosdok/id00000988 2012-03-03T13:13:15.450Z 2023-08-08T10:03:16.292Z 2023-08-18T10:03:16.298Z {"identifier":"rosdok/id00000988","type":"local_id","additional":"","service":"MCRLocalID","created":"2018-06-30T12:56:38.386Z"} {"identifier":"http://purl.uni-rostock.de/rosdok/id00000988","type":"purl","additional":"","service":"RosDokPURL","created":"2018-06-30T12:56:38.582Z","registered":"2018-06-30T12:56:38.582Z"} {"identifier":"10.18453/rosdok_id00000988","type":"doi","additional":"","service":"RosDokDOI","created":"2018-06-30T12:56:39.873Z","registered":"2018-06-30T12:56:39.873Z"} {"identifier":"urn:nbn:de:gbv:28-diss2012-0025-5","type":"dnbUrn","additional":"","service":"RosDokURN","created":"2018-06-30T12:56:38.390Z","registered":"2012-03-04T03:28:09.233Z"} administrator
