Alkaline stability of quaternary ammonium cations for alkaline fuel cell membranes and ionic liquids.
M. G. Marino,Klaus-Dieter Kreuer +1 more
TL;DR: In this paper, the authors investigated the alkaline stability of 26 different quaternary ammonium groups (QA) for temperatures up to 160 °C and NaOH concentrations up to 10 mol L(-1) with the aim to provide a basis for the selection of functional groups for hydroxide exchange membranes in alkaline fuel cells and of ionic-liquid cations stable in basic conditions.

Sigmatropic rearrangements of ‘onium’ ylids
TL;DR: Sigmatropic rearrangements are chemical processes defined by mechanisms involving unimolecular migration of sigma-bonds with concomitant redistribution of one or more pi-bonding within the broader class of Sigmatropic processes.

Quaternary centres bearing nitrogen (α-tertiary amines) as products of molecular rearrangements
TL;DR: The scope, limitations and specificities of some of these rearrangements of quaternary centres bearing a nitrogen substituent are reviewed in order to illuminate their synthetic potential.
