Tetraethylammonium hydrogen carbonate (TEAHC), simply obtained by saturating a methanol solution of tetraethylammonium hydroxide (TEAOH) with carbon dioxide, reacts with amines in acetonitrile at room temperature affording, after the addition of a suitable alkylating reagent, the corresponding alkyl carbamates. The reaction yields (53-98% isolated products) depend on both the nature of the alkylating reagent and the nucleophilicity of the amine. Amines bearing a leaving group at the ¦Ø-position give the corresponding cyclic carbamates (48-56% isolated yields) as a result of an intramol. nucleophilic substitution; no addition of alkylating reagent is needed. The mildness of the reaction conditions and the stability of the reagent, together with its easy and cheap preparation, make this procedure a valuable alternative to the methodologies reported up to now.
