Abstract
It Has been found that ethyl 2-oxoindoliden-3-ylidene cyanoacetate (2a)reacts with B-napthol to yield 1:1 adduct.structure 6a rather than isomeric 9was established for the reaction product based on IR and C13NMP SPECTRA. SIMLARLY 3-Dicyanoethylideneindene-2-one(2b)reacts with b-napthol to yield spiro compounds 6b.the mechanism proposed for the formation of 6a,b was demonstrated in char1.
