The acylation of 1-cyclopropylpropene with acetyl fluoroborate leads to the rearrangement of the obtained cyclopropylcarbenium ion into cyclobutyl and homoallyl ions, the stabilization of which leads mainly to the corresponding fluoro ketones.During the acylation of 1-cyclopropyl-2-methylpropene the addition of the acylium ion to the carbon atom adjacent to the three-membered ring is observed in addition to the formation of the products from the rearrangement of the cyclopropylcarbenium ion (the respective fluoro ketones of the cyclobutane and homoallylic series), and this leads to ketones containing a three-membered ring.In reaction with acetyl fluoroborate 1,2-dicyclopropylethylene mainly forms a compound of the tetrahydrofuran series.
