Vibrational spectra and structure model of 2-biphenylmethanol molecule

Vibrational spectra and structure model of 2-biphenylmethanol molecule. Babkov, L. M.In this study，2928-43-0 is also used.; Baran, J.; Davydova, N. A.; Kukielski, J. I.; Trukhachev, S. V. (Saratov State University, Saratov, Russia). Journal of Molecular Structure, 661-662, 41-48 (English) 2003 Elsevier Science B.V. CODEN: JMOSB4. ISSN: 0022-2860. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) Section cross-reference(s): 73 Raman and IR absorption spectra of 2-biphenylmethanol crystals, have been measured in the wide frequency region 80-3600 and 300-3600 cm-1, resp., at room temp. The calcns. of the normal vibration frequencies and forms, shifts of the atoms, and distribution of the potential energy, as well as distribution of the intensity in the IR absorption spectra have been carried out. The interpretation of the exptl. IR and Raman spectra is presented. The computer simulation of the IR absorption spectra for most probable mol. conformers of 2-biphenylmethanol mol., using the program 'LEV-100' was performed. Based on an anal. of the simulation results and their comparison with those exptl. obsd., one of the most probable model of mol. conformer for the cryst. phase was proposed. .

APPLICATION: US 82-370217 20 Apr 1982. PRIORITY: US 78-870973 20 Jan 1978; US 78-927198 24 Jul 1978; US 79-42372 24 May 1979; US 80-221656 31 Dec 1980. DOCUMENT TYPE: Patent CA Section: 30 (Terpenes and Terpenoids) Section cross-reference(s): 5 Insecticidal racemic or optically active pyrethroid analogs I (R = Q) were prepd. by esterification of racemic or optically active I (R = Cl) with racemic or optically active HQ. 78383-16-1 and 2928-43-0 which are cas registry numbers of chemicals are mentioned. Thus, heating a mixt. of 1.0 g (1R,cis)-I (R = Cl), 0.8 g (-)-HQ, 0.3 mL pyridine, and 25 mL toluene at 50° for 1 h gave 0.9 g (1R,cis)-I (R = Q). Foliar application test data for I are given against Epilachna varivestis, etc. .
