Abstract

trans-1, 4-Dialkoxycyclohexanes afford very abundant [MH-ROH]+ ions upon chemical ionisation (CI), in contrast to the cis-isomers, suggesting anchimeric assistance in the alcohol elimination from the MH+ ions of the trans-diethers. Collision induced dissociation (CID) measurements of the [MH-ROH]+ ions, obtained from various suitably deuterium labelled stereoisomeric 1-ethoxy-4-methoxycyclohexanes, indicate formation of ...
