Carbon-carbon ternary centers can also be assembled by nucleophilic addition. Manfred Braun of the Universitat Diisseldorf has devised (Angew. Chem. bit. Ed. 2004,43,514) the Lewis acidic Ti complex 8. Exposure of a racemic benzylic silyl ether such as 7 to allyltrimethylsilane in the presence of the catalyst 8 leads to the alkylated product 9. Racemic tertiary benzylic ethers are also converted to the alkylated quaternary centers in > 90% . [Pg.94]
