- 中文摘要: [ Me/sub 2/Al(.mu.-NiPr/sub 2/)/sub 2/MgMe ] /sub 4/(A) reacted with chloroform to give the starting material [ Me/sub 2/Al(.mu.-NiPr/sub 2/)/sub 2/MgCl ]/sub 2/ (4) in high yield. Compound (4) underwent metathesis with LiR (R=t-C/sub 4/H/sub 9/, C/ sub 6/H/sub 5/) to give [ Me/sub 2/Al(.mu.NiPr/sub 2/)/sub 2/MgR ] /sub n/(n=1, 2). Compound (A) reacted with pyrazole (Pz) in a molar ratio 1:1 to produce [ Me/sub 2/Al(.mu.-NiPr/sub 2/)/sub 2/Mg(Pz) ] /sub 2/ (1), and in a molar ratio 1:3 to produce degradation products [ Me/sub 2/Al(.mu.-Pz)/sub 2/ AlMe/sub 2/ ] /sub 4/ (2) and [ Me/sub 2/Al(.mu.-Pz)/sub 2/ Mg(.mu.-Pz)/sub 2/AlMe/sub 2/ ] (3). Compound (A) reacted with AlMe/sub 3/ to give [ Me/sub 2/Al(.mu.-NiPr/sub 2/)/sub 2/Mg(.mu.-Me )/sub 2/AlMe/sub 2/ ] (8). Compound (8) isomerized to [ Me/sub 2/Al(.mu.-NiPr/sub 2/)(.mu.-Me) Mg(.mu.-NiPr/sub 2/)(.mu.-Me)AlMe/sub 2/ ] (7) upon heating. Compound (7) was also obtained from reaction of AlMe/sub 3/ with Mg(NiPr/sub 2/)/sub 2/ in a molar ratio 3:1. The crystal structures of compounds (2), (3), and (8) were determined by X-ray diffraction analysis.
