| Abstract: | The reactions of the complexes (dcype)NiH]2, 1, (dippe)NiH]2, 2, and (dtbpe)NiH]2, 3, with a mixture of BEt3 and Super-Hydride (LiHBEt3) afforded sigma-borane nickel(0) compounds of the type (dcype)Ni(sigma-HBEt2)], 4, (dippe)Ni(sigma-HBEt2)], 5, (dtbpe)Ni(sigma-HBEt2)], 6, respectively, with the concomitant formation in each case of (dcype)2Ni2)(H)3]BEt4], 7, (dippe)2Ni2(H)3]BEt4], 8 and (dtbpe)2Ni2(H)3]BEt4], 9, respectively. X-ray crystal structures are reported for 4 and 8.The reaction of BEt3 and LiHBEt3 was also reviewed in detail. |
