Therefore, tertiary carbocations are more stable compared to secondary, primary, and methyl, respectively. Another case is that of alcohols. Primary alcohols can be oxidized to aldehydes and carboxylic acids (two levels). Secondary alcohols can go only one level of ketones, and tertiary alcohols cannot be oxidized at all.
Two different methods for sampling of primary, secondary, and tertiary aliphatic and aromatic amines in air have been developed for improving amine analysis in air. The aim was to have a quick method for direct sampling of amines at defined times, for example, for material testing as well as for longterm measurements of amines by diffusive sampling during field studies without sampling

An efficient strategy for primary, secondary and tertiary aliphatic C(sp3)H vinylation of amides with alkenylboronic acids is reported. These reactions are catalyzed by visiblelight organic photoredox agents. Regioselective C(sp3)H vinylation of amides is controlled by a 1,5hydrogen atom transfer of an amidyl radical generated in situ.
