Conclusions

13C-13C SSCC values across the triple bond in activated acetylenes are determined primarily by the σ-electronic properties of substituents. The enhanced sensitivity of1Jcc in acetylene derivatives to substituent effects also asserts their possible utility in estimating the electronegative properties of substituents.
