An alkoxide-catalyzed hydrosilylation of cyclic imides to isoquinolines was realized via tandem reduction and rearrangement. Using TMSOK as the catalyst and (EtO)2MeSiH as the reductant, a series of cyclic imides containing different functional groups were reduced to the corresponding 3-aryl isoquinolines in moderate to good yields. The scenario of the reaction pathway was supposed to involve the reduction of imides to ω-hydroxylactams, which underwent rearrangement in the presence of a base catalyst, and then the carbonyl reduction, followed by siloxy elimination.
Superelectrophilic Tscherniac amidomethylation of aromatics with N-hydroxymethylphthalimide in trifluoromethanesulfonic acid

N-Hydroxymethylphthalimide in trifluoromethanesulfonic acid (triflic acid) reacts readily at room temperature with benzene, halo-, polyhalo- and halonitrobenzenes to give high yields of the corresponding α-amidomethylated products. The scope of the α-amidomethylation reaction is substantially extended by the studied system, which is considered to involve diprotonated N-hydroxymethylphthalimide as the de facto superelectrophilic reagent.

N-Alkyl and N-benzyl substituents are displaced from 2,4,6-triphenylpyridinium cations by nucleophilic azide, phthalimide, succinimide, and sulphonamide anions.This enables the conversion of primary alkyl- and benzylamines into azides, and primary (with potential for inversion or labelling) and secondary amines.
