The addition of organometallic compounds to SCHIFF bases, hydrazones, and oximes was studied. It is shown that, contrary to statements in the literature, hydra-zones and oximes may give rise to the same type of C-alkylation and C-arylation as already known for SCHIFF bases.
A method for forming an imine comprises reacting a first reactant comprising a hydroxyl functionality, a carbonyl functionality, or both a hydroxyl functionality and a carbonyl functionality with a second reactant having an amine functionality in the presence of ordered porous manganese-based octahedral molecular sieves and an oxygen containing gas at a temperature and for a time sufficient for the imine to be produced.
Diethylsilane exhibits remarkable reactivity relative to typical hydrosilanes in the reduction of carbonyl compounds, imines, and amides catalyzed by Au nanoparticles.

2-Iodobenzoyl chloride reacts with ketimines in acetonitrile at 100° undercarbonmonoxidepressure in the presence of a catalytic amount of a palladium catalyst together with triethylamine to afford the corresponding spiroisoindolinones in high yields.

Tandem processes involving catalysts can offer unique and powerful strategies for converting simple starting materials into more complex products in a single reaction vessel. Imines were synthesized directly from alcohols via a tandem catalytic process using manganese octahedral molecular sieves (OMS-2) as catalyst. The synthesis proceeds through two steps: an oxidation of the alcohols to carbonyls
