Stereoselective synthesis of enynes by nickel-catalyzed cross-coupling of divinylic chalcogenides with alkynes
Silveira, Claudio C.,Braga, Antonio L.,Vieira, Adriano S.,Zeni, Gilson
, p. 662 - 665 (2003)
(Z,Z)- and (E,E)-divinylic selenides and telurides undergo direct coupling with terminal alkynes in the presence of a nickel/CuI catalyst at room temperature to give (Z)- and (E)-enyne systems in good yields and with complete retention of configuration.
