摘要：

An alkylperoxonickel(II) complex with hydrotris(3,5- diisopropyl4- bromo- 1- pyrazolyl) borate, [Ni(II)ACHTUNGTRENUNG(OOtBu)(TpiPr2, Br)] (3a), is synthesized, and its chemical properties are compared with those of the prototype nonbrominated ligand derivative [Ni(II)ACHTUNGTRENUNG( OOtBu) ACHTUNGTRENUNG(TpiPr2)] (3b; TpiPr2 = hydrotris( 3,5- diisopropyl- 1- pyrazolyl) borate). Same synthetic procedures for the prototype 3b and its precursors can be employed to the synthesis of the TpiPr2, Br analogues. The dimeric nickel(II)- hy- droxo complex, [(Ni(II)TpiPr2, Br) 2ACHTUNGTRENUNG(m- OH) 2] (2a), can be synthesized by the base hydrolysis of the labile complexes [Ni-II(Y)(TpiPr2, Br)] (Y= NO3 (1a), OAc (1a')), which are obtained by the metathesis of NaTpiPr2, Br with the corresponding nickel(II) salts, and the following dehydrative condensation of 2a
