Overview

The product exhibits potential exothermic hazards at higher temperatures.

Trans-β-methylstyrene was used in the epoxidation reaction of an oxidant solution with a solution of dichloromethane, where nickel is used as a catalyst and benzyltributylammonium bromide as a phase-transfer agent.Trans-β-methylstyrene was used in the preparation of exo-chromans by the oxa analogue of the Povarov reaction.
