Abstract
A series of new [1-aryl-2-arylamino-5,6-diphenyl-4(1H)-pyridinylidene)propanedinitriles 3a-e has been synthesized by the reaction of N 1 ,N 2 -diarylamidines la-e with (2,3-diphenylcyclopropen-l-ylidene)propanedinitrile (2). Structures of 3a-e have been assigned on the basis of NMR spectra and NOE experiments.
