Ammonia was efficiently N-alkylated into tertiary amines by room-temperature photoirradiation at >300 nm in the presence of platinized titanium dioxide suspended in alcohols, such as methanol, ethanol, and ethylene glycol.A couple of processes, photocatalytic dehydrogenation of alcohols and thermal hydrogenation of an imine intermediate, account for the ammonia N-alkylation.
