A METHOD OF PREPARING A SOLID COMPOSITE OF A COMPLEX OF BORON HALIDE AND METAL HALIDE WITH A SUPPORT WHICH COMPRISES COMPOSITING WITH AN INERT SUPPORT A METAL HALIDE IN WHICH THE HALOGEN ATOM IS OTHER THAN FLUORINE AND IN WHICH THE HALOGEN ATOM IS OTHER THAN GROUP CONSISTING OF IRON, NICKEL, COBALT, PLATINUM, PALLADIUM, CHROMIUM, MOLYBDENUM, TUNGSTEN, VANADIUM, TANTALUM, TITANIUM, ZIRCONIUM AND MANGANESE, THEREAFTER TREATING WITH HYDROGEN HALIDE IN WHICH THE HALOGEN ATOM IS CHARACTERIZED BY A LOWER ATOMIC WEIGHT THAN THE HALOGEN ATOM OF SAID LAST MENTIONED METAL HALIDE TO A METAL TURE SUFFICIENT TO CONVERT SAID METAL HALIDE TO A METAL HALIDE IN WHICH THE HALOGEN ATOM IS OTHER THAN IODINE AND OF LOWER ATOMIC WEIGHT THAN THE ORIGINAL HALOGEN ATOM OF SAID METAL HALIDE, AND REACTING WITH BORON HALIDE AT A TEMPERATURE SUFFICIENT TO FORM SAID COMPLEX WITH A SUPPORT.
