trans-Stilbene is used in the manufacturing of dye lasers, optical brighteners, non-steroidal synthetic estrogens such as diethylstilbestrol, fosfestrol and dienestrol. It is used as a phosphor and a scintillator. It is also involved in transition metal catalyzed asymmetric epoxidation and dihydroxylation. Further, it is used as raw material in organic synthesis.
Asymmetric dihydroxylation with N-methylmorpholine N-oxide, in the presence of osmium tetroxide and dihyroquinidine 4-chlorobenzoate, has been described: Org. Synth. Coll., 9, 383 (1998).
Reaction with NBS in aqueous DMSO gives the bromohydrin: Org. Synth. Coll., 6, 184 (1988). Oxidation to benzil can be effected with iodine in DMSO: Synthesis, 131 (1991).
