✦ Synopsis

Isomerisation of Benzilphenylosazones in the Presence of Acids

Isomerisation process of the three stereomeric benzilphenylosazones (Z,Z E,E and Z,E) in a melt of trichloracetic acid and in an ethylacetate solution of conc. sulfuric acid is studied. It is established that the convertion runs irreversibly to the stable E,E‐isomer at low acid concentration. The process is reversible at high acid concentration and the equilibrium state depends on this concentration.
