Abstract

Azetidin-2-ones were prepared by addition of phenylacetic acid chloride to substituted benzal-anilines in DMF. The effect of temperature and substituents at the benzal-anilines on the reaction mechanism was investigated carrying out the reaction in DMF d7 in an NMR probe of a Bruker 400-MHz spectrometer at 25 and 60° C. Proton signals, arising from two kinds of intermediates a 2-phenyl-N-(α-chlorobenzyl)-acetanilide (6) and a nitrogen- ...
