Yj. Chen et Cn. Li, AN ALTERNATIVE METHOD TO PREPARE NITRILE OXIDES FROM PRIMARY NITRO-COMPOUNDS BY USING THIONYL CHLORIDE AND TRIETHYLAMINE, Journal of the Chinese Chemical Society, 40(2), 1993, pp. 203-207
The dehydration of PhCH2NO2 (1a), PhCOCH2NO2 (1b), and MeOOCCH2NO2 (1c
) with SOCl2 in the presence of Et3N gave three corresponding nitrile
oxides. Each nitrile oxide was trapped by various dipolarophiles to ob
tain the cycloadducts of 2-isoxazolines.
