Abstract
A process for the preparation of N-carbonylarylimine of the general formula I: ##STR1## in which Ar represent an aryl radical and R represent a phenyl or t-butoxy radical, by desulphonating the compound of the general formula II. ##STR2## The compounds of formula II are novel when R is t-butoxy.
