Nuclear Magnetic Resonance Spectroscopy. Carbon-13 Chemical Shifts in Acyclic and Alicyclic Alcohols

TLDR: In this article, the chemical shifts of a variety of acyclic and alicyclic alcohols have been determined by high resolution spectroscopy with the aid of proton decoupling.

Abstract: The chemical shifts of ^(13)C in a variety of acyclic and alicyclic alcohols have been determined by high resolution nmr spectroscopy with the aid of proton decoupling It has been found that there are rather good linear relationships between carbon chemical shifts in alcohols and analogously constituted hydrocarbons, wherein a methyl group replaces the hydroxyl group The linear correlation coefficients for relationships of the general type δ_CROH = Aδ_CRCHa + B are better than 098 for shifts of corresponding ɑ (directly attached hydroxyl), β, y, and δ carbons for a variety of primary, secondary, and tertiary acyclic alcohols and cyclohexanols carrying both axial and equatorial substituents The shifts of the carbons of a number of cycloalkanols have been investigated in hope of providing information about conformations in medium-sized ring compounds
