Dauben and coworkers reached similar conclusions on the basis of their extensive investigations of the photochemistry of 3-alkyl-6,6,9,9-tetramethyl-A3 5(10 -hexalins (122)217. Direct irradiation of these compounds leads to the formation of 129 and 130 due to secondary irradiation of the initially formed triene 128, which exists as an equilibrium mixture of conformers cZc-128 and cZz-128 (equation 48). Their results showed that as the steric bulk of the 3-substituent increases, the rate of disappearance of starting material decreases and the cyclobutene (129) bicyclo[3.1.0]hex-2-ene (130) product ratio...

Effect of Temperature and Cell Divider. Increase in temperature (runs 5 and 13) lowers current efficiency but does not affect product distribution. Using divider (runs 5 and 14) decreases current efficiency but shifts product distribution drastically in favor of octalin over hexalin. Similar results were obtained by Benkeser et al. (I) in their electrochemical reduction of aromatic compounds in methylamine.

The importance of conformational effects on photoreaction pathways are clearly seen with substituted hexatrienes. For the opening of hexalins (54), Ae ratio of vinylcyclobutenes (56) to bicyclo[3.1.0]hex-anes (57) depends on Ae size of the substituent R in accordance with a preponderance of one or the other conformer of the photogenerated hexatriene (55). In addition, when the (cZc) conformer is favored, the...

In the irradiation of 3,10-dimethyl-3,5-hexalin (23) it has been found that five ethers are formed, the cyclopropyl ether (24) arising from the bicyclobutane and the ethers (25-28) coming from other intermediates. The amounts of these various products formed depend upon the concentration of methanol present during the irradiation. 

The reaction according to eq. (25) leads exclusively to cw-hexahydronaph-thalene (cw-hexaline), a product which is otherwise accessible only by multistep synthetic pathways [72], Macomber [73] reported the [2+2+2] cycloaddition reaction of diphenylacetylene or C2(C02Me)2 and ntfo-dicyclopentadiene or norbomylene, respectively, in the presence of -Cp-cobalt dicarbonyl or -methyl-Cp-cobalt dicarbonyl in refluxing toluene.

Hexalin [Du Pont]. TM for cyclohexanol (usually shipped with 2.25% methanol as antifreeze). 

One reason for the rather low quantum yields for product formation from Z-1,3,5-hexatriene is thought to be that the ground state conformer distribution is heavily weighted in favor of the relatively unreactive fZf-conformer . Substituents and structural constraints have quite substantial effects on the conformer distribution, and hence on the quantum yields and distribution of products obsCTved. These effects are well understood, having been worked out independently by Havinga and coworkers, who examined the photochemistry of various 2-alkyl- and 2,5-dialkyl-l,3,5-hexatrienes (120 and 121, respectively) , and by Dauben and coworkCTs with their studies of the photochemistry of substituted 6,6,9,9-tetramethyl-A -hexalins (122). Both bodies of work were predicated on the effects of substituents at the 2- and/or 5-positions of the...
