General description

10-Undecenoic acid undergoes copolymerisation with ethylene using the metallocene catalyst system Cp2ZrCl2 / methylaluminoxane.

Application

10-Undecenoic acid has been used to study the methods and mechanisms for the formation of molecular monolayers on silicon surface. It was used as starting reagent in the syntheses of pheromone (11Z)-hexadecenal and agriculturally important insect pheromones.
