ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), trans-1,2-diphenylethylene, which has a vapor pressure of 8.81X10-4 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere.
Chanawanno et al. prepared and studied the antibacterial activity of pyridinium stilbene 199a, 199b and quinolinium stilbene 203a, 203b. 1,2-Dimethylpyridinium iodide 196 reacted with 4-dimethylaminobenzaldehyde 198 and 4-ethoxybenzaldehyde 197 separately to produce PAM 199a in 61% yield and PET 199b in 66% yield.
1 Ιουλ 2005 · We investigated the reaction of (Z)-1,2-diphenylethene (cis-stilbene) with various brominating reagents and solvents following directions in standard organic chemistry manuals.
