WebThere are four equivalent C-H bonds, thus we can that the dissociation energy for a single C-H bond would be: D(C − H) = (1660 / 4)kJ / mol = 415kJ / mol The bond energy for a given bond is influenced by the rest of the molecule. However, this is a relatively small effect (suggesting that bonding electrons are localized between the bonding atoms). WebApr 4, 2024 · Herein, we describe an organocatalytic approach for straightforward acylation of C(sp3)–H bonds employing readily available aldehyde as “acyl source” involving dehydrogenative coupling of aldehydes with ether, amine, or benzylic C(sp3)–H bonds. The developed method affords a broad range of ketones under mild conditions.
