Article abstract of DOI:10.1016/j.tet.2003.12.068

Reactions of diethylphosphonoalkyl α-aminonitriles with 1,1′-carbonyl-diimidazole or 1,1′-carbonyl-di-(1,2,4-triazole) and O-substituted hydroxylamines under acidic conditions gave 3-alkoxy-4-imino- imidazolidin-2-ones, whereas in presence of triethylamine 4-alkoxy(aralkoxy) imino-imidazolidin-2-ones were formed.
