Abstract

The Hofmann-1,6-elimination reaction of 5-methyl-picolinyl(2)-trimethylammonium hydroxide led to unexpected products. By the low-temperature decomposition 2-methyl-5-hydroximethyl-pyridine and as main product di-(2-methyl-5-picolinyl)-ether are formed. Two of the four possible isomers of the cyclic dimer are separated by gas chromatography. In the NMR spectra of [2.2](2,5)pyridinophanes pseudo-geminal downfield shifts are observed.
