Polymer-supported RCpCpTiCl2 (Cp =η5-C5H4; RCp = η5-RC5H4) have been prepared and reduced by i-C3H7MgBr in situ , then used in catalytic isomerization of1,5-hexadiene. The isomerization of 1, 5-hexadiene leads to a mixture of cyclic and linear products. The ratio of cyclic to linear product depends on the nature of the supporter and the substituent on the cyclopentadienyl ring. The former contributes themost, for example, silica supported Cp2TiCl2 gave cyclic-linear ratio of 99/1,while for polymer-supported Cp2TiCl2 species, linear compounds are the major products and the ratio of cyclic to linear product changes with different R groups on the cyclopentadienyl ring.
