On the First Example of an Inverted Sequence S A N S C in a Pure Polar Compound

Abstract
Six homologues of the new series 4–[4′-nitrobenzyloxy] benzylidene-4′-alkoxyaniline are presented. The reentrant sequence I N SA Nre SC was found for the first time in the pure compound : 4–[4′-nitrobenzyloxy]ben-zylidene-4′-undecyloxyaniline, while the dodecyloxy derivative presents the inverted sequence ISANSCS1.
