Conversion of a primary amine to a labeled secondary amine by the addition of phenolic group and radioiodinationTo preserve the nucleophilicity of amino compounds during conjugative radioiodination, a new method for converting primary amines to phenolic secondary amines was developed. Amino acids were ...

An improved process is provided for the selective production of secondary amines and primary amines by bringing together under reaction conditions a tertiary amine or a secondary amine with oxygen or an oxygen- containing gas in the presence of an activated carbon catalyst, the improvement which comp...
Primary amine reacts with epoxy resin is the reaction of hydrogen atom connected to the primary amine nitrogen atom with epoxy group, the primary amine changes into secondary amine and then converts into tertiary amine. Reaction principle is shown in follows. ① Reaction with epoxy to get second...
While the mechanism of this reaction bears similarity to that of the typical ammonolysis of esters, as shown in Fig. 5, the nucleophilicity of the [NH2BH3]− anion is much stronger than that of the neutral amine molecules in ammonilysis. Although the amidoborane anion ([NH2BH3]−) an...
