Tetramethyleneethane-d8

Tetramethyleneethane (TME) is a triplet non-Kekule molecule that is currently the source of a difference between theory and experiment.The best theory places the energy of the triplet about 1 kcal/mol below the singlet at an angle of twist of 50 deg C about the central carbon-carbon bond.However, the triplet ESR spectrum shows no splitting between the x- and y-lines, indicating that the zero field parameter, E, is 0 or very small.If it is the former, that would be consistent with a D2d configured TME.In order to explore this point by removing proton hyperfine coupling, TME-d8 was prepared.Again, no splitting was observed between the x- and y-lines for TME-d8.This sets an upper limit for E of approximately 0.001 cm-1.

The low-temperature photochemistry of s-cis acyclic 1,3-dienes

In this article we have examined the very low-temperature photochemistry of three acyclic 1,3-dienes. We have used high-temperature deposition techniques combined with matrix isolation to create samples enriched with the thermally meta-stable s-cis form. This technique has allowed us to examine the separate photochemistry of the s-cis and s-trans conformers. Our results suggest the presence and the absence of barriers on the excited-state surface. In particular, we have found that the electrocyclic closure and s-cis-s-trans photochemical isomerization stops at 15 K for 2,3-dimethyl-1,3-butadiene-d10. The closure occurs at higher temperatures in solution but is slowed by a deuterium isotope effect. The s-trans conformer of EE-2,4-hexadiene shows almost no photo-reactivity in a matrix under 254 nm irradiation, but the s-cis conformer is rapidly converted to ZE-2,4-hexadiene (ZE-HXD). The photoreactivity of ZE-HXD is similar in that there is a relatively quick conversion of the s-cis conformer under these conditions, with only a very slow conversion of the s-trans to photoproducts.
