Radicals more stable than 157 should be formed on thermolysis of l-vinyl[2.2]paracyclophane (164) and trans-/S-carbomethoxy-1 -vinyl-pi. 2]paracyclophane (165) 113>. When heated at 165 °C, crystalline 164 gave the expanded ring cis-[4.2]paracyclophan-l-ene (168) in 90% yield photolysis of 164 in methanol at room temperature also gave (13%) 168. When heated at 100 °C in benzene, trans-765 gave cis-3-carbo-methoxy[2.2]paracyclophan-l-ene (169).

In order to increase the quantum yield of cis -> trans isomerization, it is proposed to use aromatic hydrocarbons such as anthracene as a carrier of the quantum chain process. (Z,E)-(cis-18) and (E,E)-l,4-di(3,5-di-tert-butylstyryl) benzene (trans-18) underwent mutual isomerization on biacetyl sensitization with a quantum chain process to afford a 4>c >t value of 1.2-1.3 in a cis isomer concentration of 1 X 10 M [96]. The quantum chain process proceeds through the energy transfer from the trans triplet (H ) to the ground state cis isomer ( c). On addition of anthracene (AN) as a quencher or a carrier of the excited state, the quantum...

Substituted coumarins, such as psoralen and a number of its derivatives, exhibit strong photobiological effects on bactria [6,7], viruses [8], and mammalian skin [9,10] in presence of light. Coumarin itself is also knovm to show interesting photochemical behavior, particularly dimerization [11-17], in polar and non-polar solvents. In polar solvents such as ethanol, the cis head-to-head dimer is formed presumably via interaction of excited singlet coumarin with its groud state, while in non-polar solvents such as benzene, trans head-to-head dimer is formed via the triplet state. No detailed study on the photolysis of coumarin, however, has been done in the solid state [11,18] nor in the inclusion state.

Product from cycloaddition of benzene and trans-butadiene is predominates. To benzene trans-butadiene adds more readily, it +n cycloaddition is photochemically allowed. Formation of charge transfer complex between two ground state molecules or an exciplex between excited state of one molecule and ground state of other may lower the energy barrier to this pericyclic reaction, it +7c cycloaddition may occur is case of two aromatic substrates also. For examples, dimerization of naphthalene and anthracene is very common (shown on next page). 

One of the compoimds commonly determined as its Phase 1 metabolite is benzene, whieh is metabolized to phenol in the body (see Chapter 23, Section 23.13 and Figure 23.16). The phenol metabolic product of benzene is measured in urine, usually by gas chromatography. The urine sample is treated with perchlorie aeid to hydrolyze phenol conjugates and the phenol is extracted into diisopropyl ether for ehromatographic analysis. Two other metabolic products of benzene, trans,trans-mueonie aeid and S-phenyl mercapturic acid, are now commonly measured as more-speeifie biomarkers of benzene exposure.
