Abstract
A method of producing an ethynyl aromatic aldehyde comprises reacting a protected copper(I) acetylide salt with a halogen substituted aromatic compound to produce a protected ethynyl aromatic aldehyde. The protected ethynyl aromatic aldehyde may be deprotected to yield an acetylene terminated aromatic aldehyde which is useful for making acetylenic Schiff's base monomers and conductive polymers thereof.
