Bonding and organic and inorganic reactivity of metal-coordinated phosphinoenolates and related functional phosphine-derived anions

An overview of the bonding modes of functional phosphine-derived carbanions, carbon-based reactivity, and oxygen-based reactivity is given. Under the bonding modes of functional phosphine-derived carbanions, discussed are the bonding modes of E (κ 2-P,C), F (κ2-P,O), G (κ 2-P,N), H (κ1-O), I (υ 2-P,C), J (υ2-P,O), K (υ-k1(O):k2(P,O), and L (υ 3-P,C,O). Under carbon-based reactivity, focus is on the: protonation reactions; reactions with P-Cl bonds; reactions with heterocumulenes; reactions with alkynes, tetracyanoethylene, and azo compounds; reactions with coordinated organonitriles; reaction with iodine or N-iodosuccinimide; and reactions with metal electrophiles. Finally, topics discussed under oxygen-based reactivity include reactions with: P-Cl bonds, alkynes, a coordinated benzoyl ligands, and metal centers.
