Diisobutylaluminium phenyl tellurolate

Diisobutylaluminium phenyl tellurolate, a highly air- and moisture-sensitive reagent, prepared by reaction of diisobutylaluminium hydride with diphenyl ditelluride, undergoes an in situ addition to a,jS-unsaturated carbonyl compounds, leading to the corresponding jS-phenyltelluroaluminium enolate. This intermediate is hydrolysed by aqueous HCl into jS-phenyltelluro compounds or smoothly affords an aldol reaction with aldehydes to give a-hydroxyalkyl-jS-phenyltellurocarbonyl compounds.
