WebMar 31, 2024 · Boronic acid derivatives are important compounds in synthetic organic chemistry because they are useful and less toxic substrates for various coupling reactions. 1 Among them, 1,8-diaminonaphthalene (H 2-dan)-protected boronic acids (R-B(dan)) are known as stable derivatives, which do not react under standard conditions for … 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. Soc., 2013, 135, 3375-3378.

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 ...
