Abstract

Mono- and di-2,2,2-trichloroethyl acetals have been selectively prepared in good yields by acid-catalyzed alcohol exchange with 2,2,2-trichloroethanol and dimethyl or diethyl acetals. A nonacidic and aprotic reductive cleavage using activated zinc dust in ethyl acetate or THE regenerates the carbonyl.
