  A Direct Synthesis of Selenophenes by Cu-Catalyzed One-Pot Addition of a Selenium Moiety to (E,E)-1,3-Dienyl Bromides and Subsequent Nucleophilic Cyclization

  摘要：

  An efficient protocol for the synthesis of selenophenes and selanyl selenophenes has been achieved by a simple one-pot reaction of 1,3-dienyl bromides and 1,3-dienyl-gem-dibromides respectively with KSeCN catalyzed by CuO nanoparticles. Several aryl, alkenyl, heteroaryl, and alkyl substituted selenophenes were obtained with a broad array of functional group tolerance. This is found to be a general methodology for chalcogenophenes being effective for the synthesis of thiophenes too.

  a versatile precursor for the synthesis of conjugated 1,3,5-trienic derivatives of controlled configuration. In this paper, we describe the stereocontrolled synthesis of E,E,Z, E,E,E and Z,E,Z isomers of α-bromo-ω-substituted-1,3,5-hexatrienes and 1,6-disubstituted-1,3,5-hexatrienes. The synthesis is based on palladium-catalysed single or double cross-coupling reactions between the three isomers − 1E
