Abstract
Abstract Diphenyl ether,1,4-diphenoxybenzene, and some substituted diaryl ethers have been irradiated in solution. The reactions observed are: (1) cleavage of the ether bond(s) followed by H-abstraction from the solvent yielding phenols and benzene derivatives, and (2) a photo-Claisen type rearrangement yielding 2- and/or 4-hydroxybiphenyl derivatives. The product distribution was found to depend on the solvent. The o/p ratio of rearrangement of diphenyl ether was found to be concentration dependent, the o-isomer increasing at the expense of the p-isomer on dilution.
