Abstract
Alkyl halide exchange may be catalyzed under mild conditions in homogeneous solution by ligand stabilized, low valent, coordinatively unsaturated d.sup.6 or d.sup.8 Group VIII metal complexes of the formula EQU M.sup.n X.sub.n L.sub.x wherein M is a metal of Group VIII of the Periodic Table; X is chloride, bromide or iodide; n is 1 or 2; L is a neutral ligand such as CO; trialkyl or triaryl- phosphines, arsines, amines, or stibines and the like; x is an integer from 2-4 and L.sub.x represents x neutral ligands which may be the same or different. In this manner the halide group of one alkyl halide may be replaced by the halogen of another alkyl halide by a process of alkyl halide exchange.
