Stang, Peter J.,Murch, Paul
, p. 1378 - 1380 (1997)
Reactions of β-functionalized alkynyliodonium triflates with PhSeK or PhTeLi afford novel, push-pull alkynyl phenyl selenides and tellurides in good yields.
Ytterbium(III)-catalyzed three-component reactions: Synthesis of 4-organoselenium-quinolines

4-Organoselenium-quinolines were synthesized via model multi-component Povarov (MCR) reactions between p-anisidine, ethyl glyoxylate and ethynyl(phenyl)selane, catalyzed by the Lewis acid Yb(OTf)3, with yields ranging from moderate to good. This method is advantageous in that there is no requirement for an oxidant and that the reaction has a wide scope. These 4-organoselenium-quinolines allowed access to 4-alkynyl-quinolines, which were synthesized via copper free Sonogashira cross-coupling reactions catalyzed by a new palladium catalyst that employs an oxazoline derivative as a ligand. A plausible mechanism was proposed based on HRMS studies.

Diphenyl diselenide reacts with terminal alkynes at room temperature in DMSO in the presence of catalytic amounts of copper iodide to give good to excellent yields of alkynyl phenyl selenides. The reaction occurs under neutral conditions and the solvent a

Hydroaluminuation and bromination of 1-(phenylselenyl)-1-alkynes were studied and compared with the rate of hydroalumination and bromination of the corresponding alkynylsilanes.
