WebThe development of efficient methods for facilitating N–C(O) bond activation in amides is an important objective in organic synthesis that permits the manipulation of the traditionally … WebA hypothesis for activation of amides toward hydrolysis establishes that the amide bond could be significantly weakened by twisting the amide bond in the reactant, and thus, imposing orthogonality between the nitrogen lone pair and the carbonyl π-system. This would destabilize the reactant by breaking the nN-π*CO delocalization. lantun ja ruutin laulut
