    • 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 , wherein R and R 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 AR (R )z and (I), wherein A is selected from oxygen, nitrogen, phosphorus or sulfur; R , R , and R are selected from alkyl radicals containing from 1 to 6 carbon atoms; R and R 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.
    • 一种用于生产芳族锂化合物的高纯度溶液的改进方法,包括使粒径在10-300微米范围内的颗粒状碱金属与式ROR 1的通常液体的醚类溶剂中的芳基卤反应,其中R 在选自下式的化合物的路易斯碱化合物存在下,R 1选自含有3至6个碳原子的烷基基团:R 2 R 3(R 4) z和(I),其中A选自氧,氮,磷或硫; R 2,R 3和R 4选自含有1至6个碳原子的烷基; R 5和R 6独立地选自氢或含有1至6个碳原子的烷基; y为4〜6的整数; 但当A为氧或硫时,z为零; 当A为氮或磷时,z为1,并且其醚与芳基卤的摩尔比至少为1.3:1,路易斯碱与芳基卤的摩尔比为0.01至0.50; 和产品的过程。
