Abstract

Highly functionalized benzylic zinc chlorides are prepared by the direct insertion of commercially available zinc dust into the corresponding benzylic chlorides in the presence of stoichiometric amount of lithium chloride. These polyfunctional zinc organometallics react with various electrophiles leading to a broad range of functionalized products.
