1H NMR spectroscopy, measurements of dipole moments, and the Kerr effect have been used to study the conformational structure in solutions of 3-X-3-oxo-6,7-benzo-1,5,3-dioxaphosphepines (X=Me, Et, Ph, Cl, NEt2, OEt, OPh). On the basis of x-ray diffra

Two of the four possible dibenzo [d,g][1,3]dioxocin-12-one conformers are identified in solution from IR and Raman spectra. The experimental enthalpy difference between boat-chair (BC) and twist T) conformers of 0.7 kcal mol- is obtained from tempera

1H and31P dynamic NMR, vibrational spectroscopy, and consideration of dipole moments have shown that 2-chloro-2-thiono-4,5;7,8-dibenzo(4,4′-dimethyl-6,6′-di-tert-butyl)-1, 3,2-dioxaphosphocene and its 2-ethoxy derivative are conformationally hete

Internal rotation around (Y)Csp2- X (X=;C, O; Y=;Csp2 , O) bonds is considered. A calculation scheme, taking into account heteroatom lone pair interactions, is used. Wide literature information, concerning the rotation discussed here, is gathered and

Ab initio calculations of CH2CH-PF2 and CH2CH-PCl2 were performed to investigate their conformational isomerism. It has been shown that both compounds have two conformers: the cis and the eclipsed. The concept of group orbital interactions was used t
