The application of C[1]magnesocenophanes in dehydrocoupling catalysis is reported. Two new cycloalkylidenebridged C[1]magnesocenophanes were synthesized and structurally characterized. These C[1]magnesocenophanes were used as catalysts in amine−borane dehydrocoupling and, more extensively, in amine−silane cross-dehydrocoupling. The substrate scope, involving different aliphatic, aromatic, and benzylic amines, was probed and the mechanism of this cross-dehydrocoupling catalysis was investigated.

The synthesis and characterization of bis(di-tert-butylindenyl) germanium(ii), tin(ii) and lead(ii) complexes are reported, which includes the first structurally authenticated example of a bis(indenyl)germanocene.

(Pyrrolidinyldimethylsilyl)tetramethylcyclopentadienide complexes of lithium, sodium and potassium were synthesized and characterized, including crystal structure determinations. The lithium cyclopentadienide compound was used as a Cp transfer reagent to prepare the corresponding ferrocene, stannocene and plumbocene.
