Processes for the preparation of haloalkylamines and tertiary aminoalkylorganometallic compounds are disclosed. The haloalkylamines can be prepared by direct reaction of an amine with an &agr;,&ohgr;-dihaloalkane or an &agr;,&ohgr;-dihaloalkene. Tertiary aminoalkylorganometallic compounds can be prepared by reacting selected tertiary haloalkylamines with an alkali metal at a temperature greater than 45&deg; C. in hydrocarbon solvents.

Processes for preparing tertiary aminoalkylorganometallic compounds

An improved process for producing high purity solutions of aryllithium compounds comprising reacting a particulate alkali metal having a particle size in the range of 10 to 300 microns, with an aryl halide in a normally liquid etheral solvent of the formula ROR.sup.1, wherein R and R.sup.1 are selected from the group of alkyl radicals containing from 3 to 6 carbon atoms, in the presence of a Lewis base compound selected from compounds of the formula: R.sup.2 AR.sup.3 (R.sup.4).sub.z and ##STR1## wherein A is selected from oxygen, nitrogen, phosphorus or sulfur; R.sup.2, R.sup.3, and R.sup.4 are selected from alkyl radicals containing from 1 to 6 carbon atoms; R.sup.5 and R.sup.6 are independently selected from hydrogen or alkyl radicals containing one to six carbon atoms; y is an integer from 4 to 6; but when A is oxygen or sulfur, z is zero; and when A is nitrogen or phosphorus, z is one, and provided there is a mole ratio of ether to aryl halide of at least 1.3 to 1 and a mole ratio of Lewis base to aryl halide of from 0.01 to 0.50; and products of the process.
