GRAPHICAL ABSTRACT

ABSTRACT

The Kabachnik-Fields reaction of pyrene-1-carboxaldehyde with dibenzyl phosphite and aliphatic amines in methanol led to the formation of dimethyl amino(pyren-1-yl)methyl-phosphonates, in some cases accompanied by dimethyl hydroxy(pyren-1-yl)methyl-phosphonate. These results are exclusive for the above compounds, in all other studied cases (aromatic aldehydes, aromatic amines) the mixtures of several aminophosphonates were obtained.
