Metallocenes with interlinked cyclopentadienide ligands are commonly referred to as ansa‐metallocenes or metallocenophanes. These can have drastically different properties than their unbridged parent compounds. While this concept is best known for

The Lewis acidities of a series of [n]magnesocenophanes (1 a–d) have been investigated computationally and found to be a function of the tilt of the cyclopentadienyl moieties. Their catalytic abilities in amine borane dehydrogenation/dehydrocouplin

A bis(dicarba[2]aluminocenophane) was synthesized by reduction of a corresponding dichloro precursor with 1,3-β-diketiminate magnesium(I). The bis(aluminocenophane) is stable under an inert gas atmosphere and was characterized in solution and in the

We describe two new types of reactivity involving silicon-bridged [1]ferrocenophanes. In an attempt to form a [1]ferrocenophane with a bridging silyl cation, the reaction of sila[1]ferrocenophane [Fe(η-C5H4)Si(H)TMP] (12) (TMP = 2,2,6,6-tetramethylp
