WebThe borylation occurs selectively at the methylene C-H bonds of the cyclopropane ring in high diasteroselectivities. The cyclopropylboronate esters can be converted to trifluoroborate salts, boronic acids, cyclopropylarenes, cyclopropylamines, and cyclopropanols. C. W. Liskey, J. F. Hartwig, J. Am. Chem.

Indeed, according to the Evans p K a table the cyclopropane C − H bond ( p K a ≈ 46) is more acidic than the C − H bond on the central carbon in propane ( p K a ≈ 51). We know that, in general, the acidity of C − H bonds follows the order s p > s p 2 > s p 3. This is because the more s -character in an orbital, the more ... pop larkins lorry
