compounds were obtained in good to excellent yields through an uncatalyzed three-component reaction by treatment of secondary amines with polyformaldehyde and electron-rich alkenes in acetonitrile as solvent at ambient temperature. The reactions proceeded with the formation of iminium ions, through a Mannich-typereaction, as the key intermediates for the generation of the target products. Single crystal

A highly regioselective C–C bond cleavage method of enones has been devised from the ruthenium-catalyzed deaminative coupling reaction with simple amines. The analogous catalytic coupling reaction of enones with anilines has led to a regioselective Cα–Cβ bond cleavage of enones in forming N-alkylanilines and 2,4-disubstituted quinolines. The reaction profile study showed the formation of a β-aminoimine
A surface treatment includes a functional component and a linking component, wherein the linking component is capable of hydrogen bonding and/or covalently linking with the functional component and is capable of hydrogen bonding and/or covalently linking with the surface to form a treated surface. The surface treatment provides a beneficial property to the surface when the surface treatment is bonded to the surface.
