Deamination of 1-Aminoalkylphosphonic Acids: Reaction Intermediates and Selectivity

Deamination of 1-aminoalkylphosphonic acids in the reaction with HNO₂ (generated "in situ" from NaNO₂) yields a mixture of substitution products (1-hydroxyalkylphosphonic acids), elimination products (vinylphosphonic acid derivatives), rearrangement and substitution products (2-hydroxylkylphosphonic acids) as well as H₃PO₄. The variety of formed reaction products suggests that 1-phosphonoalkylium ions may be intermediates in such deamination reactions.

Hydrothermal water enabling one-pot transformation of amines to alcohols via supported Pd catalysts

The simple, direct conversion of amines to alcohols is quite rare and remains challenging. Here, with the unique catalytic role of hydrothermal water, two green and one-pot strategies were proposed...
