    Description / Table of Contents: Preparation of Spiro[ox- or -thiazolidin(perhydroox- or -thiazolopyrimidines)] from 2-Alkyl-2-ox- or -thiazolines and IsocyanatesMethyl isocyanate and 2-alkyl-2-ox- or -thiazolines form cyclic 2 : 2-adducts 4. Similar adducts are obtained with aryl isocyanates if catalytic amounts of boron trifluoride etherate are added to prevent the formation of the known 2 : 1-adducts 2 and 3. The structure of the new adducts is elucidated by chemical means.
    Notes: Methylisocyanat und 2-Alkyl-2-oxa(thia)zoline bilden cyclische 2 : 2-Addukte 4. Mit Arylisocyanaten werden analoge Addukte erhalten, wenn durch Zusatz katalytischer Mengen Bortrifluorid-ätherat die Bildung der bekannten 2 : 1-Addukte 2 und 3 verhindert wird. Auf chemischem Wege wird die Struktur der 2 : 2-Addukte aufgeklärt.
