Vn. Yarovenko et al., N-15 NMR-STUDY OF THE MECHANISM OF THE REACTION OF AMIDOXIMES WITH NITRILES IN THE PRESENCE OF ZNCL2 AND HCL, Russian chemical bulletin, 43(4), 1994, pp. 627-629
The structures of complexes formed during the transformation of amidox
imes into 1,2,4-oxadiazoles by the action of nitriles in the presence
of zinc chloride and HCl were studied by N-15 NMR spectroscopy.
