Polymeric Reagents. Preparation of Resins Containing Polyvinylperbenzoic Acid Units¹

Several synthetic routes to bead polymers containing peracid functional groups have been explored. Thus, swellable or macroreticular styrene-divinylbenzene copolymers containing approximately 1 mequiv of perbenzoic acid functional group per gram were prepared from resins containing vinylbenzoic acid, vinylbenzoyl chloride, or vinylbenzaldehyde units. The polymeric peracids were stable and could be used and regenerated several times without degradation. The use of the polymers in a simple epoxidation reaction is described.
