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.

3-dienes 5a–g were prepared and transformed to the corresponding tricarbonyliron complexes 6. The efficiency of 6 as tricarbonyliron transfer reagents and the activity of 5a–g for the catalytic complexation with either nonacarbonyldiiron or pentacarbonyliron was investigated. It was shown that the catalytic complexation with pentacarbonyliron using the azadiene 5b as catalyst in dioxane at reflux can

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
