Abstract
Reaction of cyclopropylcarbinyl alcohols 1 with hexachloroacetone and triphenylphosphine resulted in 8040% yields of the Corresponding cyclopropylcarbinyl chlorides 4 regioselectively, with no trace of the homoallylic chloride 2 or the chlorocyclobutane derivative 6a. Similar reaction of 1 with bromine and triphenylphosphine, in dimethylformamide, gave 6540% yields of the cyclopropylcarbinyl bromide 5 with trace ...
