Alkynes benzeneselenenyl chloride

Benzeneselenenyl chloride adds to alkynes to produce mixtures of trans-alkene adducts. For example, the addition of benzeneselenenyl chloride to the alkyne (18) produces the alkene (19), which can be transformed to yield the unusual diene (20 equation 16). Alkynic alcohols give anti-Miukovnikov addition products under kinetic control. The reaction is thought to proceed dirough the selenirenium ion (21 equation 17). Selenium electrophiles add to a, -alkynic caibonyl moieties to produce cis adducts in good yield (equation 18). ... [Pg.521]
