Abstract

Abstract Aus bestimmten Kombinationen von Nitron 1 und Isocyanid 2 erhält man in Gegenwart von Ether–Bortrifluorid nicht 4-Imino-1, 2-oxazetidine 3, sondern deren Ringerweiterungsprodukte, die 4-Imidazolidinone 4. In zwei weiteren Fällen werden statt 3 oder 4 die 1, 2, 4-Oxadiazolidin-5-one 5 gefunden.–Die Konstitution 4 wird durch Röntgenstrukturanalyse des im Titel genannten Vertreters 4c bewiesen.
