## Abstract The sydnones **1a**β**c** react with the 4,5βdihydroβ__v__βtriazoles **2a**β**c** by long refluxing at 110β 140Β°C affording __via__ nonβisolable adducts with elimination of CO~2~ and N~2~ and rearrangement a mixture of 4,5βdihydropyrazoles **3a**β **c**, 3βpyrazolecarbaldehyde anils **4
I-Aryl-4-methylene-5-morpholino-v-triazolines 1 were reacted with halomethyl radicals generated by reaction of=halo methanes 2 with benzoyl peroxide or copper(I)chlori In theformer case the corresponding I-aryl-4-trihaloethyl-v-triazoles 1 and I-aryl-4-halomethyl-v-triazoles 4 were formed. In the
