摘要：

[Me(2)Al(mu-NiPr2)(2)MgMe]( )4 (A) reacted with chloroform to give the starting material [Me(2)Al(mu-NiPr2)(2)MgCI](2) (4) in high yield. Compound 4 underwent metathesis with LiR (R = t-C4H9, C6H5) to give [Me(2)Al(mu NiPr2)(2)MgR](n) (n = 1, 2). Compound A reacted with pyrazole (Pz) in a molar ratio I:I to produce [Me(2)Al(mu-NiPr2)(2)Mg(Pz)](2) (1), and in a molar ratio 1:3 to produce degradation products [Me2Al(mu-Pz)(2)AlM e(2)](4) (2) and [Me(2)Al(mu-Pz)(2)Mg(mu-Pz)2AlMe(2)] (3). Compound A reacted with AlMe(3) to give [Me(2)Al(mu-NiPr2)(2)Mg(mu-Me)(2)AlMe(2)] (8). Compound 8 isomerized to [Me(2)Al(mu-NiPr2)(mu-Me)Mg(mu NiPr2)(mu-Me)AlMe(2)] (7) upon heating. Compound 7 was also obtained from reaction of AlMe(3) with Mg(NiPr2)(2) in a molar ratio 3:1. The crystal structures of compounds 2, 3, and 8 were determined by xray diffraction analysis.
