O-Methyl oximes have been employed as nucleophiles in reactions with ketenimines derived from sulfonyl azides and terminal alkynes to form N-alkylidene N′-tosylacetimidamide derivatives. The optimized conditions involved the use of CuPF6 and i-Pr2NEt in MeCN at 65 °C. Both O-methyl aldoximes and ketoximes were tolerated under the optimum conditions.
