Photoreactions of Nitrodiphenyl Ethers
Photoinduced nucleophilic substitution reactions of thirty p-nitrodiphenyl ethers including the herbicides nitrofen and chlornitrofen with a variety of amines were examined. The reaction took place by liberating nitrophenoxide or nitrite, depending on the substituents. Nitrofen liberated mainly nitrophenoxide by reactions with pyridine and 4methylpyridine to give N-phenylpyridinums, whereas chl...
متن کاملPhotoreactions in Phycomyces
Sporangiophores of Phycomyces in stage IV b have been stimulated by parallel light in test areas 0.2 mm. wide. The growth responses to large stimuli are very large, owing probably to light scattered within the specimen. For medium stimuli the sensitive zone coincides with the growth response zone obtained previously and excludes the region of maximum stretch. Sustained stimulations were used to...
متن کاملCreating favorable geometries for directing organic photoreactions in alkanethiolate monolayers.
The products of photoreactions of conjugated organic molecules may be allowed by selection rules but not observed in solution reactions because of unfavorable reaction geometries. We have used defect sites in self-assembled alkanethiolate monolayers on gold surfaces to direct geometrically unfavorable photochemical reactions between individual organic molecules. High conductivity and stochastic...

متن کاملPhotoreactions of Partially Blinded Whip-tail Scorpions
The experiments dealt with in this paper were devised to ascertain (1) the relative effectiveness as photoreceptors of the whip-tail scorpion's median eyes, lateral eye groups, and cutaneous sensitive areas, and (2) the effect on orientation produced by symmetrical and by asymmetrical interference with the photoreceptive mechanism. Each of the receptors was eliminated unilaterally and bilateral...
