General description

The product exhibits potential exothermic hazards at higher temperatures.

Application

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.

An oxa analogue of the well-known Povarov reaction has been developed for the synthesis of 3,4-dihydrobenzopyrans (chromans). The reaction involves the formal inverse electron demand [4 + 2] cycloaddition reaction of in situ-generated cationic aryl 2-oxadiene oxocarbenium ions with alkenes.

According to literature and our research, the styrene polymerization mechanism is identified by alpha-methylstyrene (AMS). This study investigated the basic exothermic behavior of styrene and its major derivatives, AMS, and trans-beta-methylstyrene (TBMS), by two calorimeters, differential scanning calorimetry (DSC) and
