摘要：

Coupling constants J13C-H monosubstituted ethylenes containing as first atom of the substituent group O, S, C and N in divinyl ether, divinyl sulphide, methyl vinyl ketone and N vinyl 2-pyrrolidone were measured. The constants were found to be linearly correlated with those of the corresponding monosubstituted methanes. Empirical expressions are given which reproduce 12C-H spin-spin couplings for saturated and ethylenic systems as a function of substituent electronegativity and C-substituent bond length. © 1969.
