Copper(II)-mediated intramolecular cyclization of (Z)-chalcogenoenynes: Synthesis of 3-halochalcogenophene derivatives
Barancelli, Daniela A.,Schumacher, Ricardo F.,Leite, Marlon R.,Zeni, Gilson
experimental part, p. 6713 - 6718 (2012/01/04)
We present our results on the cyclization of (Z)-chalcogenoenynes mediated by copper(II) salts to afford 3-halochalcogenophenes in satisfactory yields through an intramolecular 5-endo-dig cyclization. The methodology was carried out using CuCl2

The first Suzuki-Miyaura reactions of 2,3,5-tribromothiophene are reported. These reactions provide a convenient and site-selective approach to 5-aryl-2,3-dibromothiophenes, 2,5-diaryl-3-bromothiophenes, and 2,3,5-triarylthiophenes. Georg Thieme Verlag St
