The reaction of sulfone anions with trialkylboranes followed by thermalisomerization of the obtained boron compounds in the presence of excess borane–methyl sulfide complex and by alkaline hydroperoxide oxidation yields primary alcohols.
Metalation of methallylbenzenes with BuLi gave dilithio derivatives which were dialkylated with methyl bromide. Derivatives of cross conjugated dianions are obtained preferentially to linear ones. The parent trimethylenemethane dianion2 was obtained by metalation of isobutene. Energies and atomic net charges of these and related molecules were calcualted. The question of the aromaticity of these systems
