“…In fact, the mixture of NiCl 2 and NaBH 4 is used to prepare nickel boride, 4 a reducing agent for many functional groups: azide, 5 nitrile, 6 NO bond, 7 alkene 8 and haloalkane. 9 NiCl 2 was used in the regioselective rearrangement of dienols, 10 ring-opening of epoxide, 11 nickel(II)/chromium(II) chloride-mediated addition to aldehydes or ketones, 2,3 Suzuki cross-coupling, 12 Biginelli reaction, 13 reductive Heck-like reactions, 14 nickel-catalyzed cross-coupling reaction of Grignard reagents 15 and homo-coupling reactions. 16 Abstract (A) Suzuki cross-coupling with ArBr and ArI can be carried out with PhB(OH) 2 in good yields using NiCl 2 ·6H 2 O as a catalyst precursor.…”
