Reductive Removal of Phenylseleno Groups from α-Phenylseleno Carbonyl Compounds by Means of Tellurolate Anions
摘要:
Alpha-phenylseleno carbonyl compounds are reduced to the corresponding selenium free carbonyl compounds by reaction with organic and inorganic tellurolate anions.
α-Bromo,α-phenylseleno ethyl acetate and α,α-bisphenylseleno ethyl acetate react with aromatic hydrocarbons under Friedel-Crafts conditions to give α-aryl, α-phenylseleno ethyl acetates, which by reduction with thienylditelluride (catalytic) and sodium borohydride led to the corresponding aryl acetic acids.
