摘要

N-Alkylarylamines ArNHR can be prepared by the direct alkylation of primary aromatic amines with alkyl halides, 1 aryl sulfonates, 2 dialkyl phosphites, 3 or dimethyl oxalate, 4 provided that a large excess of the starting amine is used. However, the separation of the product from the reaction mixture is difficult. Tertiary N, N-(dialkyl) arylamines are invariably byproducts5 because the N-alkylarylamines produced in the first step are more ...
