1,1-Diphenylethylene is an aromatic hydrocarbon with chemical formula C14H12.

Properties[edit]

1,1-Diphenylethylene mediates polymerization of methyl methacrylate or styrene. Meditation of 1,1-Diphenylethylene generates low molecular weight polymer.[1] Dibenzofulvene is an analogue of a 1,1-Diphenylethylene.[2]

Synthesis[edit]

1,1-Diphenylethylene is technical prepared by alkylating benzene by styrene in presence of a zeolite beta and subsequent dehydrogenation.[3]

styrene + benzene → 1,1-diphenylethane → 1,1-diphenylethylene + H2
