OXYTELLURATION OF OLEFINS TO (β-ALKOXY- AND β-HYDROXY-ALKYL)ARYLTELLURIUM DIHALIDES AND THEIR REACTIONS WITH REDUCING AGENTS AND AQUEOUS NaOH
Treatment of olefinic hydrocarbons with phenyltellurium tribromide or a mixture of diphenylditelluride and bromine in alcohol affords (β-alkoxyalkyl)phenyltellurium dibromides in fair to good yield (alkoxytelluration of olefins).Various aryltellurium tric
Treatment of olefins with phenyltellurium(II) or (IV) species in alcohol at room to reflux temperature for 1-24 h produces the corresponding (2-alkoxyalkyl)phenyltellurium dihalides in good yields, the reaction being trans-stereoselective and highly regioselective.
