CHARGE CONTROL IN THE FORMATION OF COMPLEXES OF PHENOL WITH ETHYLENE DERIVATIVES CONTAINING ORGANOELEMENTAL GROUP IVB SUBSTITUENTS

The DELTAv(OH) frequency shifts of phenol and the DELTAv(R) resonance components of these shifts in the IR spectra of phenol H-complexes wit h ethylene derivatives containing various substituents including organ osilicon, organogermanium, and organotin groups have been studied. The relationship between DELTAv and DELTAv(R) and the values that charact erize the influence of substituents on the effective charges of the do uble bonded carbon atoms was established; the latter values have been calculated previously using ab initio quantum chemical methods. The ef fective charges for the compounds with organoelemental substituents ha ve been calculated. It has been elucidated that of the two types of po ssible interactions, charge controlled and orbital controlled, occurri ng in the formation of a complex of a hard acid, phenol, with the stud ied ethylene derivatives, the former is predominant.
