WebFeb 16, 2024 · The key principles of ligand design for enantioselective C–H activation reaction are thus twofold; ligands must both be capable of creating a steric environment that affords stereocontrol and must increase reactivity of a transition metal catalyst, accelerating the rate of the reaction. WebIn this section we consider the relative basicity of several nitrogen-containing functional groups: amines, amides, anilines, imines, and nitriles. When evaluating the basicity of a nitrogen-containing organic functional group, the central question we need to ask ourselves is: how reactive (and thus how basic) is the lone pair on the nitrogen?

WebOne important method of preparing 1º-amines, especially aryl amines, uses a reverse strategy. Here a strongly electrophilic nitrogen species (NO 2(+)) bonds to a nucleophilic carbon compound. This nitration reaction gives a nitro group that can be reduced to a 1º-amine by any of several reduction procedures. WebThe reactivity of a functional group can be modified by other functional groups nearby. Functional group interconversion can be used in retrosynthetic analysis to plan organic synthesis .
