Preparation and properties

4-Vinylcyclohexene dioxide is prepared by epoxidation of 4-vinylcyclohexene with peroxybenzoic acid.^[5] Its viscosity is 15 mPa·s.^[5]

Safety

4-Vinylcyclohexene dioxide, like other volatile epoxides, is classified as an alkylating agent.^[5] VCD has toxic effects on fertility. It is a killer of oocytes, eggs in a female's ovaries, in immature ovarian follicles in mice and rats.^[7][8][9]

In pest control, it has been used as an ovotoxic agent for reducing rat fertility.^[10]
