O-(p-Toluenesulfonyl)-N-methyl-, -N-ethyl-, and -N-isopropil-hydroxylamines and O-mesitylenesulfonyl-N-methylhydroxylamine were prepared.The N-methyl and N-ethyl derivatives were found to react with tertiary amines and triphenylphosphine to give the corresponding N-(alkylamino)ammonium salts and P-(alkylamino)phosphonium salts, but the N-isopropyl derivative was less reactive, probably due to steric effects.These reagents also reacted with tri-n-butylborane to give the corresponding alkyl-n-butylamines.Keywords-- electrophilic aminating reagent; tert-butoxycarbonylation; di-tert-butyl dicarbonate; N-(methylamino)ammonium salts; P-(methylamino)triphenylphosphonium salt; N-(methylamino)pyridinium salt; secondary amines
