The effects of Co(acetylacetonate)2, Ni(acetylacetonate)2, and Cu(ethyl acetoacetate)2 on the nuclear magnetic resonance spectra of a variety of alcohols and amines have been studied. Changes are produced in the spectra, which are useful for assigning the signals.

The 19F nuclear magnetic resonance spectra of β,β-difluorostyrenes and 1-difluoromethyleneindans bearing fluorine substituents in the aromatic ring have been recorded and the long-range couplings 6JF,F and 7JF,F are discussed. In each compound the larger couplings are to the olefinic fluorine trans to the aromatic ring. The couplings are maximum in the planar indans, reducing to unobservable values when non-planarity is achieved in suitably substituted styrenes. The allylic coupling 4JH,F involving olefinic fluorines shows only slight stereochemical dependence.

Abstract High resolution infrared and nuclear magnetic resonance spectra confirm the structure of cis-polychloroprene prepared by a stereospecific route. Head-to-tail, head-to-head, and tail-to-tail sequence isomerism in both as- and trans-polychloroprenes has been discovered and measured quantitatively by high resolution NMR spectroscopy. The irregularity in the microstructure of neoprenes proves to be more extensive than was previously suspected.
