Title (EN) LITHIUM DIALKYLAMIDE AND LITHIUM ALKYLENECYCLOIMIDE FORMULATIONS AND METHODS OF PREPARATION
(FR) PREPARATIONS DE DIALKYLAMIDE DE LITHIUM ET D'ALKYLENECYCLO-IMIDE DE LITHIUM ET PROCEDES CORRESPONDANTS
Abstract: front page image
(EN)A process for producing normally liquid hydrocarbon solutions of lithium dialkylamides and lithium alkylenecycloimides, essentially free of ethers and by-product gaseous alkanes derived from C¿1?-C¿4? alkyllithium compounds, comprising reacting lithium metal with a C¿5? to C¿12? secondary amine and an electron carrier compound containing at least five carbon atoms in a normally liquid hydrocarbon solvent.
(FR)Procédé de préparation de solutions d'hydrocarbure normalement liquides de dialkylamides de lithium et d'alkylènecyclo-imide de lithium, sensiblement dépourvues d'éthers et de sous-produits alcanes gazeux dérivés de composés alkyl-lithium en C¿1?-C¿4?, consistant à faire réagir du métal lithium avec une amine secondaire en C¿5?-C¿12? et un composé porteur d'électrons contenant au moins cinq atomes de carbone dans un solvant hydrocarbure normalement liquide.
