Mechanisms of the photochemical rearrangement of diphenyl ethers

The mechanism of the photochemical rearrangement of diphenyl ether (1a) was studied. Irradiation of 1a in ethanol gave 2-phenylphenol (2, 42%) and 4-phenylphenol (3, 11%) as rearrangement products, in addition to phenol (4, 30%) and benzene (5, 25%) as diffusion products. Cross-coupling experiments employing [2H10]1a demonstrated that the formation of 2- and 4-phenylphenol was an intramolecular process. Irradiation of 1a in benzene or in toluene gave biphenyls in good yields. The combined yields of rearrangement products (2 and 3) increased with increase of solvent viscosity, with a concomitant decrease in the formation of 4. All the results can be rationalized in terms of excitation of 1a to the singlet state and dissociation to a radical pair intermediate involving phenoxy and phenyl radicals. Intramolecular recombination of these radicals gives rearrangement products, and escape followed by hydrogen abstraction from the solvent gives diffusion products. When position 4 of 1a was occupied by an electron-donating substituent (1b-e), aryloxy-phenyl bond cleavage to give the corresponding rearrangement products prevailed over phenoxy-aryl bond cleavage. The opposite was the case for substrates with an electron-withdrawing substituent at position 4 (1h,i).

Mesomorphic Properties of n-Alkyl-4'-n-Pentanoyloxy-Biphenyl-4-Carboxylates

Esters in the homologous series n-alkyl-4'-n-pentanoyloxy-biphenyl-4-carboxylates (n4COOBC, n=1-12) have been synthesized.Mesomorphic properties and phase transitions have been determined using polarizing hot-stage microscopy, DSC and x-ray.Phase transitions from SA-SB crystal and hexatic (tentatively) have been observed.The relationship between the incidence of hexatic phase and molecular structure has been discussed.
