Vinylphosphonium salts are known for more than a century, but they started to attract significant attention of organic chemists only since 1964 when Schweizer demonstrated that the Michael addition of a nucleophile with a carbonyl function to vinylphosphonium salts results in phosphorus ylides, which can undergo the intramolecular Wittig reaction to carbo- and heterocyclic systems. The main synthetic routes to vinylphosphonium salts and a variety of their applications in organic syntheses are considered in detail in this review. Particular attention is given to the application of vinylphosphonium salts as versatile building blocks for syntheses of carbo- or heterocyclic systems in reactions with carbon, oxygen sulphur or nitrogen nucleophiles containing in a molecule a carbonyl function.
