/sup 1/H nmr spectra of dichloro and dihydroxy derivatives of methylcyclosiloxanes
The authors report on a continuation of an investigation of how the nature of the substituents on the Si atoms influences the character of the spectra. As objects of investigation, the authors took the dichloro and dihydroxy derivatives of cyclosiloxanes with 4 to 8 Si atoms in the ring. Shown are tables of chemical shifts of protons of CH/sub 3/ groups in chloromethylcyclosiloxanes, and chemical shifts of protons of CH/sub 3/ groups in linear methylsiloxanes and chloromethylsiloxanes. Additivity was demonstrated for chemical shifts of CH/sub 3/ group protons in dichloromethylcyclosiloxanes, and the increments of chemical shift were obtained for 8-, 10-, 12-, 14-, and 16-membered rings. It was established that the chemical shifts in the spectra of the dihydroxy derivatives are nonadditive.
