1H NMR Study of the Photoisomerization of Cinamylidene-2-Methyl-5-Chloro aniline

Layla M. N. Saleem, Ahmed S. Authman

Abstract

Cinamylidene-2-methyl-5-chloro-aniline undergoes isomerization from the trans form to the cis form under irradiation with u.v. light at room temperature. The isomerization was studied in three solvents and the % cis was found to be in the following order: in DMSO 〉 CDCl3 〉 CCl4. The rate of the process of isomerization was found to be a first order one.
