Abstract
Hydroalumination of acetylenic selenides occurs, regiospecifically and the vinyl alanes obtained as intermediates were transformed into kete ne butyltelluro (phenylseleno) acetals by the Al/Te exchange reaction using C4H9TeBr as electrophile. The stereoselectivity of the hydroalum ination of chalcogeno acetylenes was confirmed by performing the hydro lysis of the vinyl alane intermediates that results in formation of th e correponding Z phenylseleno alkenes with good yields.
