Benzocyclobutene-o-xylylene valence tautomerization: Oxygen and sulfur analogs.
Gas phase pyrolysis of o-hydroxybenzyl alcohol at 750 degrees C gave o-quinonemethide, which, on isolation, formed a mixture of the corresponding dimer and trimer. However, pyrolysis of o-hydroxy-[1-(4-pentenyl)]benzyl alcohol permitted intramolecular trapping of the intermediate o-quinonemethide, giving 3,4-trimethylene-3,4-dihydrobenzochroman. In contrast, gas phase pyrolysis of o-mercaptoben...
متن کاملO 22: Reactive Oxygen Species and Epilepsy
Seizure activity has been proposed to result in the generation of reactive oxygen species (ROS), which then contribute to seizure-induced neuronal damage and eventually cell death. Although the mechanisms of seizure-induced ROS generation are unclear, mitochondria and cellular calcium overload have been proposed to have a crucial role. We aim to determine the sources of seizure-induced ROS and ...

متن کاملLewis‐Acid‐assisted Hydrogen Atom Transfer to Manganese(V)‐Oxo Corrole through Valence Tautomerization
The kinetics of formation of the valence tautomers (tpfc⋅)MnIV(O-LA)] n+ [where LA=ZnII, CaII, ScIII, YbIII, B(C6F5)3, and trifluoroacetic acid (TFA); tpfc=5,10,15-tris(pentafluorophenyl) corrole] from (tpfc)MnV(O) were followed by UV/Vis spectroscopy, giving second-order rate constants ranging over five orders of magnitude from 10-2 for Ca to 103 m -1 s-1 for Sc. Hydrogen atom transfer (HAT) ...
