Popis:	The reduction of CoBr 2 with NaBH, in diglyme solution has been studied as a method of preparing ultrafine Co particles. The primary products are Co, H 2 , and B 2 H6. However, in the presence of the catalytic cobalt particles, B 2 H 6 is decomposed to boron and H 2 . These results are quite different from aqueous reductions of CoX 2 with NaBH 4 , where Co 2 B is the primary product (in the form of ultrafine particles).
