<p>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 ROR1, wherein R and R1 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?2AR3(R4)¿z and (I), wherein A is selected from oxygen, nitrogen, phosphorus or sulfur; R?2, R3, and R4¿ are selected from alkyl radicals containing from 1 to 6 carbon atoms; R?5 and R6¿ 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.</p> |
