由Cp*RuCl（cod）和1，2-二（苯基丙炔基）苯形成的一种配位不饱和的二苯并噻吩并噻吩，在室温下异构化为一种新的由Cp* 和一个萘醌稠合的环丁二烯配体组成的夹心配合物.另一方面，在室温下用过量的AgBF 4处理相同的二聚萘并噻吩产生四甲基富烯环丁二烯络合物。相比之下，阳离子环丁二烯络合物由分离的Cp*RuCl（环丁二烯）与过量的AgBF 4形成。
A coordinatively unsaturated ruthenacycle, which was formed from Cp*RuCl(cod) and 1,2-bis(phenylpropiolyl)benzene, was isomerized to a new sandwich complex consisting of a Cp* and a naphthoquinone-fused cyclobutadiene ligand at ambient temperature. On the other hand, the treatment of the same ruthenacycle with excess AgBF4 at room temperature produced a tetramethylfulvene cyclobutadiene complex. In contrast, a cationic cyclobutadiene complex was formed from the isolated Cp*RuCl(cyclobutadiene) with excess AgBF4.
