Phosphorylated allenes: structure and interaction with electrophiles

Data on the structures of phosphorylated allenes (PA) and their reactions with electrophiles are surveyed for the first time. It is shown that the influence of intramolecular interactions on the reactivity of the unsaturated centres is reflected in the selectivity of the reactions of PA with electrophiles. Depending on the nature of the reactants and the structure of the PA, various reaction mechanisms may operate. The bibliography includes 163 references.
