Photoelectron 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 کاملNITROIMIDAZOLES XI [I]. SYNTHESES OF DISUBSTITUTED NITROIMIDAZOLYLQUINOLINES
Reaction of substituted-aniline (8) with ethyl (l-methyl-5-nitroimidazole-2- carbonyl) acetate (9) gave 4-hydroxy-2-(l-methyl-5-nitro-2-imidazolyl)- substituted-quinolines (lo), which were converted to compound 11 with phosphorus oxychloride. Substituted-2-(l-methyl-5-nitro-2-imidazo1yl)-4.- methyl-(or phenyl-) quinolines (14) were prepared through the reaction of 2- acetyl-5-nitro-1-methy...
متن کاملFacile synthesis and preferred conformation analysis of cyclododeceno[b]indene.
Using methanesulfonic acid as a catalyst, a series of cyclododeceno[b]indene derivatives were synthesized by the cyclization of alpha-benzylcyclododecanones, which were prepared by the reactions of cyclododecanones with a variety of substituted benzyl chlorides or bromides using NaH as a base. Their structures were confirmed by mp, IR spectra, 1H-NMR, 13C-NMR, MS, and x-ray diffraction. The pre...
متن کاملIndene bioconversion by a toluene inducible dioxygenase
Rhodococcus sp. I24 can oxygenate indene via at least three independent enzyme activities: (i) a naphthalene inducible monooxygenase (ii) a naphthalene inducible dioxygenase, and (iii) a toluene inducible dioxygenase (TID). Pulsed field gel analysis revealed that the I24 strain harbors two megaplasmids of ∼340 and ∼50 kb. Rhodococcus sp. KY1, a derivative of the I24 strain, lacks the ∼340 kb el...
