ß-Nitro alcohols 1 react with triphenylphosphine/carbon tetrachloride/triethylamine under reflux to give the corresponding nitroolefins 2 in good yields (80-95%). Other groups such as tertiary hydroxyl, ether, halide etc. remain unaffected, and the nitroolefins so produced are exclusively the (E)-isomers.
