13C NMR chemical shifts of the carbon atoms of the methoxymethyl group of di‐ortho‐substituted aromatic methoxymethyl ethers

Complete 13C spectral assignments of 28 aromatic methoxymethyl ethers bearing different substituents and substitution patterns were made. While meta‐, para‐ or mono‐ortho‐substitution did not significantly affect the 13C resonances of the carbon atoms of the methoxymethyl group, di‐ortho‐substitution produced the deshielding of both carbons. This effect was more pronounced on the methylene carbon atom.
