The N-alkylation of amines is one of the most fundamental and important C–N bond-forming transformations in organic synthesis. 1 Traditionally, the N-alkylation of amines was performed with alkyl halides using stoichiometric bases. Recently, much attention has been paid to the N-alkylation of amines with alcohols as alkylating agents based on transition metal-catalyzed “hydrogen autotransfer (or hydrogen-borrowing) process”. 2 Such methods are ...
