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

Properties

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

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
