Silveira, Claudio C.,Santos, Paulo Cesar S.,Mendes, Samuel R.,Braga, Antonio L.
scheme or table, p. 3787 - 3790 (2009/04/06)
A general method for the synthesis of vinylic chalcogenides by nucleophilic and Ni-catalyzed vinylic substitution on vinylic halides by phenyl chalcogenolates is described. The reactions were regio and stereoselective for the nickel catalyzed substitution
Hydroselenation of alkynes using NaBH4/BMIMBF4: easy access to vinyl selenides
Lenard?o, Eder J.,Dutra, Luiz G.,Saraiva, Maiara T.,Jacob, Raquel G.,Perin, Gelson
, p. 8011 - 8013 (2008/03/18)
A general and easy method for the synthesis of several vinyl selenides using NaBH4 and BMIMBF4 as a recyclable solvent is described. This efficient and improved method furnishes the corresponding vinyl chalcogenides preferentially wi
Stereoconservative formation and reactivity of α-chalcogen- functionalized vinyllithium compounds from α-bromo-vinylic chalcogenides
Braga, Antonio L.,Zeni, Gilson,De Andrade, Leandro H.,Silveira, Claudio C.
, p. 595 - 596 (2007/10/03)
Bromine/lithium exchange was performed upon treatment of α-bromo-vinylic chalcogenides with butyllithium in hexane at room temperature to provide α-chalcogen-vinyllithium intermediates quantitatively. Addition of electrophiles to the lithiated compounds g
