摘要: Tetraethyl lead is reacted with 0.5 to 4 moles of CH.sub.3 X per mole of tetraethyl lead, in the presence of a catalytic amount of AlY.sub.3, wherein X and Y are independently chloride, bromide, or iodide, at a temperature up to about 130.degree. C, with the proviso that the reaction is conducted in the presence of an iodine-source selected from AlI.sub.3, elemental iodine, C.sub.1 to C.sub.4 alkyl iodide and the like. The products are tetra(methyl-ethyl) lead redistribution compounds useful as fuel antiknocks.
