摘要： Aromatic methylidene compounds of the following general formula 1 wherein R11 and R21 independently in each occurrence represent an unsubstituted or substituted alkyl or alkoxy group, a halogen, a cyano group or a nitro group, n11 and n21 are, respectively, an integer, R31 and R41 independently represent hydrogen, an unsubstituted or substituted alkyl group, an unsubstituted or substituted cycloalkyl group, an unsubstituted or substituted aromatic group, or an unsubstituted or substituted aromatic heterocyclic group and may join to complete a condensed ring, along with other types of aromatic methylidene compounds wherein the moieties attached to the naphthalene ring are attached to different positions of the ring. The preparation of the methylidene compounds is also described along with intermediate compounds and their preparation.
