Abstract

A useful model for the free allyl anion is the methyldiphosphoniopropenide 3, which is readily prepared from the diphosphinoethene 1 via the dication 2. According to NMR and X‐ray structural analyses, 3 has the E/Z configuration. Temperature‐dependent NMR studies indicate a rotational barrier of 20.5 kcal mol⁻¹ for the allyl anion fragment. (Figure Presented.)
