Multi-amino groups and nitrogen donors compound was discovered as an organocatalyst for N-alkylation of alcohols with amines in the presence of Mo(CO)6. The Mo(CO)6/organocatalyst binary system has shown to be a highly active catalyst for the N-alkylation reaction between alcohols and amines with excellent tolerance of variable starting materials bearing different functional groups. Of particular note

The one-pot synthesis of aldimines fromprimaryalcohols and amines via sequential reactions of alcohol oxidation and dehydrative condensation could efficiently be promoted by supported ruthenium h...
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.

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
Luminescent reporter compounds that are rotaxanes having the structure
where B—Z—C is a reporter molecule based on a cyanine, squaric acid, or other reporter, and K is a macrocycle that encircles and interlocks with the reporter molecule. Applications of the reporter compounds are provided, as well as reactive intermediates used to synthesize the reporter compounds, and methods of synthesizing the reporter compounds.
