The scope and limitations of a one-step synthesis of N-substituted imidobissulfates, RN(SO3K)2 (R=Me, Et, n-Pr, iso-Pr, n-Bu, iso-Bu, sec-Bu, tert-Bu, n-C6H13, cyclo-C6H11, PhCH2–, PhCH2CH2–, PhCH(CH3)–, or Ph), starting from amines and the sulfur trioxide-triethylamine complex are described. The yields are generally good (55–90%). However, with aniline only a poor (13%) yield was obtained. With tert-butylamine
