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

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.
