Solutions of permethylcyclopentadienyl-tethered titanium(IV) chlorides incorporating one double bond in their tethers were exposed in glass vessels to sunlight, which triggered their photolytical reactions providing mixtures of products. Although the formation of several different products was apparent from ¹H NMR spectra, only a single product could be identified in the crude reaction mixtures. This product was dicyclopentadiene [C₁₀Me₁₀], which arose from the recombination of the generally photodissociated C₅Me₅ radical. Amongst products that contained titanium, three complexes (3a, 3b and 4a) could be isolated after employing fractional crystallization and these complexes were characterized. The mechanism of 3a formation involves photodissociation of one η⁵-C₅Me₅ ligand from the parent complex, complemented by chlorine abstraction from another reactant molecule. Complexes 3b and 4a become formed via tether rearrangement, which starts with dissociating the tether Ti–C bond and is followed by rotating the tether, reattaching it subsequently through its available radical terminus.

将在其系链中掺入一个双键的全甲基环戊二烯基系链氯化钛（IV）的溶液在玻璃容器中暴露于阳光下，这触发了它们的光解反应，提供了产物的混合物。尽管从¹ H NMR光谱可以明显看出几种不同产物的形成，但在粗反应混合物中只能鉴定出一种产物。该产物是二环戊二烯[C ₁₀ Me ₁₀ ]，其是由通常光解离的C ₅ Me ₅自由基的重组产生的。在含钛产品中，有三种配合物（3a，3b和4a可以通过分步结晶分离得到，并对这些配合物进行表征。的机构3a中形成包括一个η的光解⁵ -C ₅我₅从父络合物配体，从另一种反应物分子被氯抽象补充。配合物3b和4a通过系链重排而形成，该过程首先是断开系链Ti-C键，然后旋转系链，随后使其重新连接通过其可用的自由基末端。
