Carbon-13 NMR of Poly(Butadiene)

Rubber Chemistry and Technology, 1972
Abstract By using the carbon-13 NMR technique, it is shown that there are no cis-1,4-trans-1,4 linkages in an n-BuLi-catalyzed poly (butadiene). The polymer consists of “blocks” of cis-1,4 units and trans-1,4 units separated by isolated vinyl units.

Carbon-13 NMR Chemical Shift: A Descriptor for Electronic Structure and Reactivity of Organometallic Compounds.

Accounts of Chemical Research, 2019
Metal-bonded carbon atoms in metal-alkyl, metal-carbene/alkylidene, and metal-carbyne/alkylidyne species often show significantly more deshielded isotropic chemical shifts than their organic counterparts (alkanes, alkenes, and alkynes).

Carbon‐13 NMR of fluorocyclopropanes

Magnetic Resonance in Chemistry, 2008
AbstractCarbon‐13 and hydrogen NMR data are presented for several cyclopropanes with one to four fluorine atoms attached to the ring. Substituents directly attached to a ring carbon are found to unshield that carbon to an extent increasing with their electronegativity, but remote substituents may have an opposite effect.

Carbon‐13 NMR study of isoxazolopyridine systems

Organic Magnetic Resonance, 1982
AbstractThe 13C NMR spectra of all azabenzenoid isoxazolopyridines and some of their chloro derivatives are discussed. All 13C resonances were unambiguously assigned by means of gated decoupled spectra, from which one‐bond and long‐range 13C1H coupling constants have been determined from line splittings.
