Applications & Uses

Uses

Useful in the preparation of nitrile ylide dimers.Benzophenone imine as ammonia surrogate. As intermediate material for synthesis of organic chemicals. Catalytic enantioselective alkylation of the benzophenone imine of glycine t-butyl ester using phosphazene (Schwesinger) bases and chiral quaternary ammonium salts yields either enantiomer of amino acid derivatives in excellent yield.

Uses

Benzophenone imine is useful in the preparation of nitrile ylide dimers.
