Dissociation of benzene dication [C6H6]2+: exploring the potential energy surface.
The singlet potential energy surface for the dissociation of benzene dication has been explored, and its three major dissociation channels have been studied: C6H6(2+) --> C3H3(+) + C3H3(+), C4H3(+) + C2H3(+), and C5H3(+) + CH3(+). The calculated energetics suggest that the products will be formed with considerable translational energy because of the Coulomb repulsion between the charged fragmen...
متن کاملElementary reactions of the phenyl radical, C6H5, with C3H4 isomers, and of benzene, C6H6, with atomic carbon in extraterrestrial environments
Binary collisions of ground state carbon atoms, C(3P j), with benzene, C6H6(XA1g), and of phenyl radicals, C6H5(XA1), with methylacetylene, CH3CCH(XA1), were investigated in crossed beam experiments, ab initio calculations, and via RRKM theory to elucidate the underlying mechanisms of elementary reactions relevant to the formation of polycyclic aromatic hydrocarbons (PAHs) in extraterrestrial e...
متن کاملCondensed phase behaviour of ionic liquid-benzene mixtures: congruent melting of a [emim][NTf2].C6H6 inclusion crystal.
The solid-liquid phase diagram of the (1-ethyl-3-methylimidazolium bis{(trifluoromethyl) sulfonyl} amide + benzene) system was determined and allowed us to identify and characterize an equimolar inclusion compound, [emim][NTf2].C6H6, with a congruent melting temperature: this type of behaviour, reported here for the first time, together with the X-ray structure of the inclusion compound lays em...
متن کاملSilyl Derivatives of the Mixed Sandwiches Cyclopentadienyl Manganese Benzene and Cyclopentadienyl Manganese Biphenyl, CpMn(C6H6) and CpMn(C6H5-Ph)
Mixed manganese sandw ich complexes containing a silyl-substituted cyclopentadienyl ring, e. g. (rj5 -C5 H4-R)Mn(7/6-C6H6) (3a c) and (775-C 5H4-R)M n(r/6-C6H5-Ph) (4a c); (R = SiM e3 (a), Si2M e_5 (b) and SiM e^'Bu (c)), were obtained in low yield via interm ediates {(r^-CsH*R)M nCl} and their reaction with phenyl G rignard reagents. Use o f the 4-trim ethylsilyl-phenyl m agnesium halide in th...
متن کاملExperimental and theoretical evidence for U(C6H6) and Th(C6H6) complexes.
The vibrational spectra of UBz and ThBz have been measured in solid argon. Complementary quantum chemical calculations have allowed the assignments of the vibrational spectra. According to the calculations, AcBz are stable molecules, as well as other species like BzAcBz and BzAc2Bz. Experimentally, there is no evidence for the sandwich compounds BzAcBz and BzAc2Bz due to the limitations in the ...
