LITHIUM-POTASSIUM EXCHANGE IN ALKYLLITHIUM/POTASSIUM t-PENTOXIDE SYSTEMS XIV. INTERACTIONS OF ALKOXIDES

Benzylpotassium containing only traces of lithium compounds is formed in the reaction of alkyllithium, potassium alkoxide and toluene over broad ranges of molar ratios of the reaction components and reaction times.This confirms that metal-metal exchange is occurring under the conditions used.The potassium alkoxide is used in stoichiometric amount for the metallation of toluene and is not only a catalyst.Use of a larger excess of potassium alkoxide leads to formation of its adduct with benzylpotassium.Various mechanisms for the above reaction are considered and formation of lithium alkoxide is assumed to help drive the equilibria towards the observed products.

Reversible Formation of a Cerium-Bound Terminal Hydride: Ce(C5Me4SiMe3)2(H)(thf)

The use of the bulky cyclopentadienyl ligand Cp′ (Cp′ = C5Me4SiMe3) to stabilize cerium hydrides has resulted in the preparation of two novel tuck-in complexes with C–H activated SiMe3groups. Subsequent reaction

Metalation of toluene and cumene with alkali metal-crown ether complexes

Metalation of toluene and isopropylbenzene with alkali metal-crown ether complexes led to the corresponding α-metalated alkylbenzenes. Treatment of the latter in succession with solid carbon dioxide, water, and hydrochloric acid gave carboxylic or dicarboxylic acids in 65-78% yield. Metalation of isopropylbenzene with sodium or potassium crown ether complexes above 90°C was accompanied by cleavage of the polyether ring with formation of organometallic compounds which then reacted with isopropylbenzene to produce 2-sodio(potassio)-2-phenylpropane and open-chain oligoether.
