✦ Synopsis

A simple synthetic procedure for the three skipped Cl2Hl2-dienediynes !-~ and the corresponding all-cis tetraenes ~-~ is reported.

In "skipped" eneynes a methylene group separates a double bond from a triple bond. The three possible skipped cyclic dienediynes, cyclododeca-4,10-diene-l,7-diyne (~), 4-methylene-cycloundeca-9-ene-l,6-diyne (~) and 4,9-dimethylene-cyclodeca-l,6-diyne (~) are not only of interest as new Cl2Hl2-isomers, but also as starting materials for the corresponding tetraenes 4, ~ and 6. Unsuccessful attempts for the synthesis of ~ and have been mentioned in the literature 1,2, whereas ~ has been prepared recently via a rather long route 3.

## Abstract Normal dodecane labeled with either carbon‐13 or deuterium at both the terminal methyl groups has been synthesized. The mass spectra and PNMR and CNMR spectra of these compounds have been measured and are reported.
