Abstract
Abstract The formation of 3-dimethylaminopropyl-lithium from the reaction of 3-chloro-1-(dimethylamino)-propane with powdered lithium in tetrahydrofuran (THF) at −25° and in cyclopentane (CP) at +49·5°, respectively, has been investigated. The kinetic and analytical determinations of this reaction were made by gas chromatography. The lithium compound was obtained in a > 90% yield in THF, although in this solvent its stability was limited even at low temperatures. In contrast in CP a more stable solution of the organometallic compound was formed, but lower yields (50% at most) were realized; this solution, unlike the THF solution, was contaminated with by-products.
