Oxaziranes stability

In their thermal stability the diaziridines approximate to the oxaziranes. As with most oxaziranes, they are stable at 100° C for short periods they are decomposed by heating at 200°C 1,2-di-n-butyl-3-ri-propyldiaziridine thus eliminates butylamine. The thermal decomposition has not yet been investigated in detail. Similarly no information is available on the reaction of radical reagents on diaziridines. 

Similar reasons may explain the considerable stability of oxaziranes toward acids. 

Since many oxaziranes have limited stability in alkaline solutions ibis, synthesis is not characterized by high yields in most oases I(. dora. however, extend the spectrum of available oxaziranes considerably, and a dramatic example of this is the preparation of the luomcri ... 

As mentioned above, the oxazirane ring ha limited stability. The products of its thermal decomposition vary considerably with the structure of the oxaoirane and also with the pyrolysis conditions. The products of thermal decomposition of the 3-arytoxaziraoes are the isomeric nitrones. This is apparently a general reaction and may be conveniently accomplished by beating solutions of the oxasiraun in...
