Abstract
A method for converting vanillin to bis(cyanate) ester monomers, comprising treating vanillin with a reductive coupling agent to form at least one olefin. The olefin or olefins are treated with hydrogen and a metal catalyst to hydrogenate said olefin. The hydrogenated olefin or olefins are treated with at least one cyanogen halide and a base in an organic solvent to afford at least one olefin monomer. The olefin monomer or monomers are purified by recrystallization or precipitation from an organic solvent.
