Abstract
N-Methylation
of amines with methanol proceeds at room temperature
in the presence of a silver-loaded titanium dioxide (Ag/TiO<sub>2</sub>) photocatalyst under UV–vis light irradiation. This method
allows facile synthesis/isolation of <i>N</i>-methylamines
bearing various functional groups including <i>N</i>-benzyl, <i>N</i>-allyl, <i>N</i>-Boc, hydroxyl, ether, acetal,
carboxamide, formamide, and olefin groups
