2-nitro- and 2,4-dinitrobenzenesulfonamides as protecting groups for primary amines
(Georg Thieme Verlag Kg, 2001-07-01)
Procedures for the deprotection of the 2-nitro- and 2,4-dinitrobenzenesulfonamides to give the corresponding primary amines were developed. The 2-Nitrobenzenesulfonyl group was effectively removed by HSCH2CH2OH/DBU or ...

Selective one-pot synthesis of asymmetric secondary amines via N-alkylation of nitriles with alcohols
(Academic Press Inc Elsevier Science, 2019-10)
The synthesis of asymmetric secondary amines (ASA) is commonly achieved by N-alkylation of primaryamines with alcohols. Here, we investigated the ASA synthesis via the direct amination of alcohols withnitriles, which avoids ...
Chemisorption on thiol-silicas: Divalent cations as a function of pH and primary amines on thiol-mercury adsorbed

Direct synthesis of N-methylurethanes from primary amines with dimethyl carbonate
(Int Union Pure Applied Chemistry, 2005-10)
The mechanism of the reaction between amines with dimethyl carbonate (DMC)
has been investigated. Whereas in the absence of bases, they give methylation and carboxymethylation reactions without selectivity (BAl2 and BAc2 ...

Direct reductive amination of aldehydes using lithium-arene(cat.) as reducing system. A simple one-pot procedure for the synthesis of secondary amines
(Pergamon-Elsevier Science Ltd, 2012-06)
A simple one-pot procedure for the direct reductive amination of aldehydes using lithium powder and a catalytic amount of 4,4′-di-tert-butylbiphenyl (DTBB) or a polymer supported naphthalene as reducing system is described. ...
Radical amination with trimethylstannylated benzophenone imine
(American Chemical Society, 2010-04)
Intermolecular radical amination reactions of various primary, secondary, and tertiary alkyl radicals by using trimethylstannylated benzophenone imine A as a novel radical acceptor to provide imines of type B are described. ...
