Conclusions
-
1.
When treated with excess diazomethane for a long time the O-alkyloximes of hexafluoroacetone form stable triazolines, which on photolysis or thermolysis give the corresponding 1-alkoxy-2,2-bis(trifluoromethyl)-aziridines.
-
2.
Ihe configurattonal stability of the 1-alkoxy-2,2-bis(trifluoromethyl)aziridines is sufficient to permit their separation into the antipodes. The derivatives with an asymmetric center in the substituent on oxygen were separated into the diasteromers by recrystallization.
