Bis(. eta. sup 5 -tricyclo(5. 2. 1. 0 sup 2,6 )deca-2,5,8-trien-4-yl) derivatives of the group IV transition metals
- Univ. of Akron, OH (USA)
Metallocene dichloride derivatives of titanium, zirconium, and hafnium were prepared from tricyclo(5.2.1.0{sup 2,6})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-dimensional {sup 1}H 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.
