Abstract

The absence of HH couplings between the methoxy group and the ring protons observed in 2‐methoxy‐, 2,6‐dimethoxy‐ and 2‐methoxy‐6‐chloropyridines is interpreted in terms of a cis conformation between the methyl fragment and the nitrogen ring atom. Other data, taken from the current literature, support this conclusion.

The ions at m/z 75 [HC (OCH 3 ) 2 ] and m/z 89 [CH 3 C (OCH 3 ) 2 ] decompose into the ion at m/z 47 and into the ions at m/z 43 and 47, respectively. These precursor ions are prepared by the loss of hydrogen (H) from the central carbon in ionized dimethoxymethane (1) and 1,1-dimethoxyethane (2). Th
