Synthesis of Tetrahedranes Containing the Unique Bridging Hetero-Dipnictogen Ligand EE' (E ≠ E'=P, As, Sb, Bi).

摘要: New synthetic pathway towards organometallic tetrahedrane derivatives [{CpMo(CO)2 }2 (μ,η2 :η2 -EE')] (E≠E'=P, As, Sb, Bi) involving a hetero-dipnictogen ligand is reported, leading to dramatic yield enhancements for already known compounds, the reduction of reaction steps and access so far unknown AsSb, AsBi SbBi complexes, which feature unseen covalent bonds between two different heavy group 15 elements without organic substituents.
