SYNTHESIS AND CONFORMATION OF R-(+)-2-(α-PHENYLETHYL)BENZOPHENONE

Masayuki Ako, Shunsuke Takenaka

Open publisher page 14 citations

Abstract

Abstract As a model of chiral benzophenone, R-(+)-2-(α-phenylethyl)benzophenone was prepared. The NMR and optical data indicate that rotations of the benzoyl and α-phenylethyl moieties are unrestricted in the range of −100 to 150°C, and therefore benzophenone skeleton is not chiral. A preferable conformation is discussed.
