摘要
Metallocene dichloride derivatives of titanium, zirconium, and hafnium were prepared from tricyclo-[5.2.1.02,6]deca-2,5,8-triene and the corresponding metal tetrachlorides. These compounds were characterized as existing primarily in the endo,endo and exo,endo forms by two-dimensional1H NMR studies. These results were unexpected, in that theory predicts primarily exo,exo isomers should be preferred. A study on bis(isodicyclopentadienyl)titanium dichloride revealed the compound to exist in two major isomeric forms: exo,endo and exo,exo. © 1990, American Chemical Society. All rights reserved.
