ACYLATION OF CYCLOPROPYLACETYLENES WITH ACYLIUM FLUOROBORATES

The direction of acylation of cyclopropylacetylenes with acyl fluoroborates depends significantly on the character of substitution in the three-membered ring.In the case of 1,1-dichloro-2-methyl-2-ethynylcyclopropane the cyclopropane ring is opened, and fluoro ketones of the allene series are formed.During acylation of cyclopropylacetylene the three-membered ring rearranges to a four-membered ring with the formation of fluoro ketones of the cyclobutane series, and the rearrangement is stereospecific to a considerable degree.
