Reactions of Indene and Indoles with Platinum Methyl Cations: Indene C-H Activation, Indole π vs. Nitrogen Lone-Pair Coordination.
Reactions of indene and various substituted indoles with [(diimine)PtII(Me)(TFE)]+ cations have been studied (diimine = ArN = C(Me) - C(Me) = NAr; TFE = 2,2,2-trifluoroethanol). Indene displaces the TFE ligand from platinum to form a stable π coordination complex that, upon heating, undergoes C-H activation with first order kinetics, ΔH‡ = 29 kcal/mol, ΔS‡ = 10 eu, and a kinetic isotope effect ...
متن کاملMetabolism of Naphthalene, 1-Naphthol, Indene, and Indole by Rhodococcus sp. Strain NCIMB 12038.
The regulation of naphthalene and 1-naphthol metabolism in a Rhodococcus sp. (NCIMB 12038) has been investigated. The microorganism utilizes separate pathways for the degradation of these compounds, and they are regulated independently. Naphthalene metabolism was inducible, but not by salicylate, and 1-naphthol metabolism, although constitutive, was also repressed during growth on salicylate. T...
متن کاملPhotoelectron Spectroscopy of Heterocycles. Indene Analogs
The He (I) photoelectron (PE) spectra of indene, indole, benzofuran, benzothiophene, 1-, 2-, 3-, 4and 6-methylindole and 4,5,6,7-tetrafluoroindole were measured and analysed. A close correlation between the jr-ionisation energies of these compounds and the eigenvalues of the corresponding HMO-orbitals is found. A qualitative scheme for the assignment of the ^-electron ionisations by orbital int...
متن کامل2-(4-Methoxyphenyl)-1H-indene
Excluding four H atoms, the molecule of the title compound, C(16)H(14)O, is almost planar, with an r.m.s. deviation of 0.0801 (2) Å. Due to p-π conjugation, the lengths of the two single bonds attached to the O atom are significantly different.
متن کاملAsymmetric synthesis of (7aS)-7a-methyl-4,5,7,7a-tetrahydro-1H-indene-2,6-dione and useful derivatives thereof.
The enantioselective synthesis of the title compound, using Meyers' bicyclic lactam methodology, is described. This compound and a few of its derivatives are useful intermediates in natural product synthesis.
