%X Rates of dehydrobromination of a series of 4-nitro-and methoxystilbene dibromides by means of acetate, cyanide or chloride ions in dimethylformamide have been measured. A product analysis was performed which indicated a strong preference for anti elimination. Probable transition state structures utilized by each of the three nucleophiles are described. Attack by the base may be at either &#946;-hydrogen (E2H) or C&#945; (E2C). The slowest reaction is with chloride ion, which also gives the highest anti/syn elimination product ratio.
