The lowest excited triplet state of triphenylboron and of the isoelectronic triphenylcarbenium ion

The lowest excited triplet state of triphenylboron and of the isoelectronic triphenylcarbenium ion. Slama, H.; Braeuchle, C.; Voitlaender, J. (Inst. Phys. Chem., Univ. Muenchen, Munich D-8000/2, Fed. Rep. Ger.). Chem. Phys.Several substances with their cas registry numbers 1586-91-0 and 960-71-4 may be metioned in this study. Lett., 102(4), 307-11 (English) 1983. CODEN: CHPLBC. ISSN: 0009-2614. DOCUMENT TYPE: Journal CA Section: 29 (Organometallic and Organometalloidal Compounds) Section cross-reference(s): 22 BPh3, C+Ph3 SbCl6- and C+Ph3 BF4- were investigated by ODMR and emission spectroscopic methods. The zero-field splitting parameters D and E and the decay rate consts. of the triplet zero-field levels as well as the phosphorescence spectra were measured. The non-zero E values indicate a symmetry lower than D3 for the Jahn-Teller unstable triplet state of all compds. The radiative decay of T1 shows a strong delocalization of the triplet wavefunction for C+Ph3, but a strong localization on the benzene rings for BPh3. This is in agreement with MO calcns. .

Asymmetric ethynes

Asymmetric ethynes. Syntheses of ethynylferrocene paradigms. Polin, Johann; Schottenberger, Herwig; Schwarzhans, Karl Eberhard ( Dipartimento Chimica "G. Ciamician", Univ. Studi Bologna, Bologna I-40126, Italy). Zeitschrift fuer Naturforschung, B: Chemical Sciences, 51(12), 1682-1690 (English) 1996 Verlag der Zeitschrift fuer Naturforschung.In this article, certain chemicals are used. Some of their cas registry numbers are 185225-31-4 and 960-71-4 CODEN: ZNBSEN. ISSN: 0932-0776. DOCUMENT TYPE: Journal CA Section: 29 (Organometallic and Organometalloidal Compounds) Synthetic methods to bifunctional ethynes were examd. Direct ethynylation, the Stephens-Castro reaction, the Pd-catalyzed Hagihara coupling, transmetalation reactions and nucleophilic addns. were evaluated in the prepn. of substituted ferrocenylethynes, of interest for potential use in nonlinear optical applications (no data). 1,4-Bis(ferrocenylethynylene)benzene, 1,3,5-tris(ferrocenylethynylene)benzene, and 9,10-bis(ferrocenylethynylene)anthracene were obtained in high yields, whereas 4-ferrocenylethynylene-2,3,5,6-tetrafluorostyrene and (ferrocenylethynylene)triphenylborate were accessible in only moderate yields. .
