- 中文摘要: The natural abundance carbon-13 nuclear magnetic resonance spectra of 3-arylsydnone, 3-aryl-4-formylsydnone, 4-acetyl-3-arylsydnone, 3-aryl-4-cyanosydnone as well as some derivatives of the above compounds have been studied. The data indicate that the electron withdrawing effect on the C/sub 4/ atom of the sydnone ring decreases in the sequence: C.ident.N>COCH/sub 3/~CHO. The solvent effect on the chemical shifts has also been investigated.
