我们报道了一种三脚架三芳氧基甲基配体支撑的双阴离子钛-萘络合物的合成和表征，这是一个罕见的η-2配位的低价早过渡金属芳烃配合物的例子。随着游离萘的释放，η的2-萘配体很容易被氮气和菲取代，形成端接的氮桥联二钛络合物和菲络合物。通过四氢呋喃的C-O键裂解生成1-氧杂-2-钛环己烷。
We report the synthesis and characterization of a dianionic titanium naphthalene complex supported by a tripodal triaryloxidemethyl ligand, which is a rare example of an η2-coordinated arene complex of low-valent early transition metals. The η2-naphthalene ligand is readily displaced by N2 and anthracene along with the release of free naphthalene, resulting in the formation of the end-on N2 bridging dititanium complex and the anthracene complex, respectively. The naphthalene complex undergoes C–O bond cleavage of THF to produce a 1-oxa-2-titanacyclohexane.
