The specific shielding effect in IjPIFi shown by aromatic solvents on polar solutes is experimentally well established. During the ten years since its discovery (1,2), many workers have investigated this effect and stereochemical aspects of it. (Papers containing many references: (3,4), more re- ce
A new method is proposed for the estimation of aromatic solvent-induced shifts(ASI.9) in carbon-13 NMR spectroscopy. The observed C-13 ASIS are shown to be useful for studing the structure elucidation.
0 NMR spectroscopic data (natural abundance) were obtained for 19 methoxy-aromatic compounds: a series of substituted anisoles with a single ortho substituent, a series of 2,Q-disubstituted anisoles, a series of 3-substituted-1, 2-dimethoxybenzenes and three multi-substituted anisole derivatives. Th
