An approach for the mild synthesis of selenoesters starting from selenoalkynes through an acid-catalyzed, redox-neutral oxyarylation reaction is reported. Br?nsted acid activation of a selenoalkyne leads to a selenium-stabilized vinyl cation, which is cap
Chalcogen electrophile induced rearrangement of 1-alkynyltrialkyl borates: Controlled syntheses of trisubstituted olefins from 1-alkynes

The reaction of 1-alkynyltrialkyl borates with sulfenyl, selenenyl and tellurenyl halides produces β-chalcogeno alkenylboranes in good yields, with a cis relationship between the boron and the chalcogen moities. Protodeborylation of these compounds by acetic acid, or by a transmetalation-protonolysis sequence, leads to vinyl chalcogenides, which can be converted to alkenes by means of a nickel catalyzed coupling with Grignard reagents. Since the last two steps occur with retention of the stereochemistry, the overall sequence represents a highly regio- and stereoselective olefin synthesis.
Convenient preparation of alkynyl selenides, sulfides and tellurides from terminal alkynes and phenylchalcogenyl halides in the presence of copper(I) iodide
Braga,Silveira,Reckziegel,Menezes
, p. 8041 - 8042 (2007/10/02)
Alkynyl selenides, sulfides and tellurides were obtained under very mild conditions by reacting terminal alkynes with phenylchalcogenyl halides in the presence of copper iodide(I).
Alkynyl sulfides and selenides from alkynyl bromides and diorganoyl chalcogenides promoted by copper(I) iodide
Braga,Reckziegel,Menezes,Stefani
, p. 393 - 394 (2007/10/02)
Alkynyl sulfides and selenides were obtained in good yields by reacting alkynyl bromides with diorganoyl disulfides and diselenides in hexamethylphosphoric triamide (HMPA) in the presence of copper(I) iodide.
