Key words: supercritical carbon dioxide, cyclization, benz-1,3-azol-2-ones, tin(II) derivatives

It was demonstrated that tin(II) 2-ethylhexanoate and tin(II) oxide are effective
catalysts for the reaction of cyclization of model arylamines o-NH₂(C₆H₄)XH (X = NH,
O, S, CH₂NH) in supercritical carbon dioxide with the formation of benzo-1,3-azol-2-
ones and 3,4-dihydroquinazolin-2-one. Optimal conditions for these reactions were
found. Possible mechanisms for these processes are proposed depending on the used
catalyst.
