Fluorinated Aminophosphonates and Aminophosphonic Acids: A Journey through Recent Advances

European Journal of Organic Chemistry
This review aims to summarize the most recent developments in the chemistry of fluorinated aminophosphonates and aminophosphonic acids, with a particular focus on literature published since the turn of 2016/2017. Fluorinated derivatives of aminophosphonates and aminophosphonic acids represent a rapidly growing area of interest due to their unique ...

Aminophosphonate Corrosion Inhibitors for Steel

Protection of Metals, 2003
The protective properties of aminophosphonic acids and their magnesium and calcium complexes were studied on the example of rotating steel cylinders specimens in soft water. Only two of the seven acids studied, namely 1,1-hydroxycarboxypropane-3-amino-di(methylenephosphonic) and hexamethylenediamine-N,N-tetra(methylenephosphonic) acids, can suppress ...

Mécanismes de Formation d'α-Aminophosphonates

Phosphorus, Sulfur, and Silicon and the Related Elements, 2003
When di-n-decylphosphonate 1a or di-benzylphosphite 1b are reacted with furan imine 2a or thiophenic imine 2b , the reaction leads to an f -aminophosphonate: 3a , 3b , or 3c following an ion- or radical-based reaction.

Asymmetric Synthesis of Aminophosphonic Acids

Phosphorus, Sulfur, and Silicon and the Related Elements, 1999
A new synthesis of chiral α- and β-aminophosphonic acids is described which involves a highly diastereoselective addition of phosphite and phosphonate anions to enantiopure sulfinimines.

The Aza-α-aminophosphonate Macrocycle

Phosphorus, Sulfur, and Silicon and the Related Elements, 2009
In order to combine the properties of aza-macrocycles and aminophosphonates, a new tetraaminophosponic macrocyclic molecule has been synthesized. This potential receptor for organic molecules as well as for metal cations was obtained by condensation, hydrophosphonylation, and deprotection. The second synthetic step was performed using di(trimethylsilyl)

Silylated iminophosphonates: Novel reactive synthons for the preparation of fluorinated aminophosphonates and aminophosphonic acids

Tetrahedron Letters, 2017
Abstract A convenient synthetic approach towards previously unknown N- and N,O-silylated α-iminophosphonates bearing fluoroalkyl groups at the imine C atom was developed. The synthetic potential of the compounds was demonstrated by their easy functionalization and the straightforward preparation of biorelevant aminophosphonates and free ...
