From the new di-Grignard reagent o-C6H4-(CH2MgCl)2[abbreviated as L(MgCl)2](i) the thermally stable metallobenzocyclopentenes [M(η-C5H4R)2L](R = Me3Si and M = Ti, Zr, or Hf; or R = H and M = Ti or Zr) and [Pt(cod)L], (ii) the η1-diacyl [[graphic omitted](:O)}]via[Hf(η-C5H4-SiMe3)2L] and CO, and (iii) the pyrophoric ML2(thf)(M = Ti, Zr, or Hf) and MgL(thf) have been obtained; X-ray analysis of the title compound to R= 0·021 shows an average ZrâCH2 distance of 2·300(2)Ã
, â CH2ZrCH2= 77·4(2)°, with the methylene carbons 0·11 and 0·12 Ã
out of the plane of the C6 ring.
从新的二格里尼试剂 o-
C6H4-( MgCl)2(缩写为 L(MgCl)2)获得了以下化合物:(i) 热稳定的
金属苯并
环戊烯 [M(η- R)2L](R = Me3Si,M = Ti、Zr或Hf;或R = H,M = Ti或Zr)和 [Pt(cod)L];(ii) 通过 [Hf(η-
C5H4-SiMe3)2L] 和 CO 获得的 η1-二酰基 [[graphic omitted](:O)}];以及 (iii) 自燃性化合物 M
L2(thf)(M = Ti、Zr或Hf)和 MgL(thf)。所得化合物的 X 射线分析结果显示,R = 0·021,平均 Zr–
CH2 距离为 2·300(2) Å,∠ Zr = 77·4(2)°,亚甲基碳与 C6 环的平面偏离 0·11 和 0·12 Å。
