π-Allylpalladium Complex
No.104(October 1999)
The present reagent 1 performs quantitative allylation with a variety of nucleophiles1,2). For example, reaction with malonic acid esters leads to allyl substituted malonate derivatives. Furthermore, addition of reagent 1 and phosphine ligands to the reactions between nucleophiles and olefins leads to the formation of a new Pd-phosphine complex within the system which functions as a catalyst for the allylation reaction to proceed smoothly. In this case using asymmetric phosphine ligands such as L* allows asymmetric allylation reaction to occur3,4).
