An 19F NMR study of diadducts of SnF4 with 19 aromatic amine oxides is reported. The results indicate that the steric nature of the ligand is probably more important than the base strength in determining the relative chem. shifts. The trans isomer is identified in all of the complexes whereas the cis isomer is present only with the less bulky ligands. In the experiment, the researchers used many compounds, for example, 3,5-Dimethylpyridine 1-oxide (cas: 3718-65-8SDS of cas: 3718-65-8).
3,5-Dimethylpyridine 1-oxide (cas: 3718-65-8) belongs to pyridine derivatives. In contrast to benzene, Pyridine’s electron density is not evenly distributed over the ring, reflecting the negative inductive effect of the nitrogen atom. Many analogues of pyridine are known where N is replaced by other heteroatoms . Substitution of one C–H in pyridine with a second N gives rise to the diazine heterocycles (C4H4N2), with the names pyridazine, pyrimidine, and pyrazine.SDS of cas: 3718-65-8
