Abstract
A novel method was developed for the synthesis of N-alkoxyacylimidoyl halide by the reaction of α-nitro ketone and alkyl halides in the presence of NaHSO4/SiO2. Nitrile oxides that are generated from α-nitro ketones by silica gel supported acid catalysts are the possible intermediate, which react with alkyl halides to form N-alkoxyacylimidoyl halides. Novel 17 N-alkoxyacylimidoyl halides were synthesized by this procedure.

- 22 Typical Procedure for the Synthesis of N-Alkoxyacylimidoyl Halide: A mixture of α-nitro ketone 1 (1 mmol), alkyl halide 2 (6 mmol) and NaHSO4/SiO2 (2.1 mmol/g, 0.5 g) in toluene (10 mL) was stirred at 80 °C for 8 h, and then the used supported reagent was removed by filtration. The filtrate was evaporated to leave the crude product, which was purified by column chromatography (hexane–EtOAc) to obtain N-alkoxyacylimidoyl halide 3 (see Supporting Information).
