Elimination Reactions of Benzaldehyde O-Benzoyloximes

E- and Z-Benzaldehyde 0-benzoyloximes 1 and 2, give benzonitriles in quantitative yield upon treatment with DBU (l,8-diazabieyelo[5.4.0]undee-7-ene) (Sehe-me 12.1). [Pg.79]

Discuss the mechanism of the elimination reaction and justify the differences in reaction rates, kn/ko and Hammett p values found for Z- and E-isomers. Interpret the experimental data and propose a reasonable structure for the transition state in both cases. [Pg.79]

A eomplete kinetie study has been earried out to determine the meehanism of the elimination reaetion for both isomers and the results obtained are eompiled in Table 12.1. [Pg.79]

The elimination reaetions exhibit general-base eatalysis in both eases. [Pg.79]

The reactions have second-order kinetics (first order in oxime and base). [Pg.80]
