Paul Knochel Andrei Gavryushin Ludwig-Maximilians Universitdt, Munich, Germany [Pg.375]

Alternate Name 2,2,6,6-tetramethylpiperidinozinc chloride-Uthium chloride complex. [Pg.375]

Solubility solution in THF miscible with majority of organic solvents, neat compound insoluble in alkanes, soluble in coordinating solvents (ethers, amines, etc.) [Pg.375]

Handling, Storage, and Precautions solution of the reagent decomposes in air, should be stored and handled under inert atmosphere. Reacts vigorously with water and aqueous solutions. Due to strong dehydrating ability, spills may cause serious damage to skin and eyes. Commercial solution in THF is a flammable liquid. [Pg.376]

Structure of the Reagent. Properties of 2,2,6,6-tetramethylpi-peridinatozinc chloride-lithium chloride such as high THF solubility and kinetic basicity are determined mainly by its assumed monomeric zincate-like structure (eq 1), which significantly differs from oligomeric Hauser bases. [Pg.376]
