Reduction of 2 cyclopropenyl esters and alcohols with lithium aluminium hydride is selective; at low temperatures (0°) the double bond is not reduced, but at higher temperatures (65°) the reduction is complete and only the cyclopropylmethanol is obtained. The reduction of the double bond is regioselective (the most stable carbanion is formed) and stereospecific (the hydride attack on the double bond

Cyclopropene-2 ylalkyl radical, obtained by tributyltin hydridereduction of 2,3-dialkylcyclopropene-2 ylmethylketones follows a very selective evolution according to the substituents in the ring. Ring enlarged products (2,3,5-triakylfurannes) and olefinic or saturated products resulting from ring cleavage can be isolated.
