Phosphorus flame retardants from renewable biomaterials offer effective, nontoxic alternatives to organbromine compounds which are stable in the environment, tend to bioaccumulate and may pose a risk to human health. Benzoquinone readily undergoes Michael addition of phosphite to generate a phosphorus-substituted hydroquinone. This hydroquinone derivative can be converted to the <i>bis</i>-acrylate by treatment with acryloyl chloride. Phosphite addition to the unsaturation of the <i>bis</i>-acrylate generates trifunctional phosphorus compounds. These compounds display good thermal stability and may serve as effective flame retardants in a variety of polymeric systems.
