Abstract: | The frequency shifts (v (OH)) of phenol and the resonance components (vr) of these shifts in the IR spectra of forty H-complexes of phenol with furan derivatives containing organic, organosilicon, organogermanium, and organotin substituents are studied. The values of v and vR are linearly related to quantum chemical parameters of the variation of the effective charges of the furan ring atoms affected by - and -interactions with organic substituents. The effect of the conjugation between an organoelement substituent and the furan ring on the effective charges is estimated. The resonance parameters (R) of organoelement substituents in derivatives of benzene, thiophene, and furan and the reasons for the non-versatility of R are considered.For report 7, see Ref. 1.Translated fromIzvestiya Akademii Nauk.
