ESR of Cation Radicals of Methyl-substituted Benzenes in a CF3CCI3 Matrix
Z. Naturforsch. 38 a, 4 2 8 4 3 3 (1983); received December 28, 1982 A new matrix, 1,1,1-trifluorotrichloroethane, CF3CCI3, has been employed in radiation chemistry studies to stabilise positive ions. As a test, positive ions of benzene, toluene, orto-, metaand paraxylene and biphenyl have been generated by y-irradiation of the solutes contained in the CF3CCI3 matrix at 77 K. The ions have been...
متن کاملPd-mediated synthesis of substituted benzenes fused with carbocycle/heterocycle.
A new Pd-catalyzed one-pot multicomponent coupling reaction for the construction of benzene ring fused with carbocycle or heterocycle under a Cu-free condition is described.
متن کاملMulti Peak ESCA Bands in Substituted Benzenes and Heterocyclic Compounds
The ESCA spectra of several substituted benzenes and heterocyclic compounds were obtained. Multi peak structures are observed in the various energy regions. The effects are generally interpreted as due to shake up phenomena involving intramolecular charge-transfer transitions between a "donor" and an "acceptor" group in the molecule. A quantitative model for such kind of phenomena is given. It ...
متن کاملAcoustic properties of binary liquid mixtures of carbon tetrachloride with benzene and substituted benzenes
The ultrasonic velocities in binary liquid mixtures of carbon tetrachloride with benzene, toluene, m-xylene, ethyl benzene and chloro benzene have been measured at entire mole fraction range at 303.15K, using ultrasonic interferometer of frequency 2 MHz. Isentropic compressibilities KS, deviations of KS from ideal mole fraction mixture law ΔKS, available volumes Va, Lennard Jones potential repu...
متن کاملENDOR studies of substituted chlorophyll cation radicals
Cation radicals of substituted chlorophyll (Chl) a molecules were characterized by EPR and ENDOR spectroscopy. The effect of substitutions of the vinyl group at position 3 and the carbomethoxy group at 13 as well as the replacement of the central magnesium atom by zinc were investigated. All major hyperfine coupling constants could be determined and assigned to specific molecular positions. Com...
