4-4-amino-Δ2-1,2,4-oxadiazolines (1) are transformed into the corresponding 2-arylamino-1,3,4-oxadiazoles (5), or thiadiazoles (6) via reaction with phenylisocyanate or phenylisothiocyanate. Followed by brief treatment of the resulting adducts (2,3) with trifluoroacetic anhydride at ambient temperature. Treatment of compounds 1 with trifluoroacetic anhydride gave 2-trifluoromethyl-1,3,4-oxadiazoles (8).تتحول مركبات أمينوأكساديازولين (1) إلى مركبات أريل أمينو أكساديازول أو ثياديازول من خلال التفاعل مع فينيل أيزوسيانات أو فينيل أيزوثيوسيانات متبوعا بمعاملتها بأنهيدريد حمض ثلاثي فلورو حمض الخل على حرارة عادية. معاملة مركبات (1) مع أنهيدريد حمض ثلاثي فلورو حمض الخل تنتج مركبات 2- ثلاثي فلوروميثيل -1،3،4- أكساديازول
