1,1-Diphenylethylene is an aromatic hydrocarbon with chemical formula C14H12.
Properties
1,1-Diphenylethylene mediates the radical polymerization of methyl acrylate or styrene. Meditation by 1,1-Diphenylethylene generates low molecular weight polymer by a termination reaction.[3] Dibenzofulvene is an analogue of a 1,1-Diphenylethylene.[4]
Synthesis
1,1-Diphenylethylene is technical prepared by alkylating benzene by styrene in presence of a zeolite beta and subsequent dehydrogenation.[5]
- styrene + benzene → 1,1-diphenylethane → 1,1-diphenylethylene + H2
