Reaction of Hydroximic Chlorides with Hexabutylditin. A Mild Method for Generation and Cycloaddition of Nitrile Oxides.

A new method for the in situ generation of nitrile oxides is reported.The reaction conditions are mild and neutral.

FRAGMENTATION OF NITRILE OXIDES WITH TRIETHYLAMINE

The formation of 1,2,4-oxadiazoles is frequently observed as a side reaction in cyclo additions with nitrile oxides generated in situ and follows from a fragmentation induced by Et3N.This latter is oxidized to N,N-diethylvinylamine, which is trapped as a cycloadduct.
