The Chemistry of Bis‐Aluminated Compounds

Abstract

In this chapter, representative examples of bis‐aluminated compound chemistry will be shown. The compounds can be classified roughly into two categories: The preparations and reactions of gem ‐dialuminated compounds will be discussed first, followed by those of aluminacycles. They have been expected to work as a dianion equivalent in organic syntheses, and have actually shown specific molecular transformations taking advantage of their capabilities. Although they possess a dianionic character, they have reasonable stability. As useful reactions of gem ‐dialuminated compounds, alkylidenation of carbonyl compounds and subsequential reactions with electrophiles will be shown. In addition, preparation of cyclic compounds via an insertion reaction of electrophiles into aluminacyles will be discussed.
