Modification of Bicyclic Phosphonates Based on Resorcinols and Its Derivatives via the Mannich Reaction

Abstract

Amino‐containing derivatives of various structures have been obtained via the Mannich reaction in a series of bicyclic phosphonates based on 2‐methylresorcinol, resorcinol, and pyrogallol with paraformaldehyde and secondary amines via the Mannich reaction. The structure and composition of the obtained compounds have been determined using 31Р and 1Н NMR spectroscopy, IR spectroscopy, mass spectrometry (MALDI‐TOF), and X‐ray analysis.

Activated carbons for applications in catalysis: the point of view of a physical-chemist

“…On the contrary, the resonance at 14.1 ppm is attributed to phosphonates, i.e. organo-phosphorous compounds containing one P-C bond, revealing that at least a fraction of phosphorous has functionalized the carbon (Benaddi et al 1998;Budinova et al 2006;Jimenez et al 2015;Puziy et al 2002;Puziy et al 2008;Sadykova et al 2015).…”
