摘要：

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