Gold(I)-catalysedtandem transmetallation (Sn→Au→As) of the stannylcarbyne [W(≡CSnnBu3)(CO)2(Tp*)] (Tp* = hydrotris-(dimethylpyrazolyl)borate) with haloarsines gives direct access to a range of novel arsinocarbyne complexes, LnM≡CAsR2, including unusual heterocyclic phenarsazininyl and arsolyl examples.
金( I )-催化的锡炔[W(≡CSn n Bu 3 )(CO) 2 (Tp*)](Tp* = 氢三-(二甲基吡唑基)硼酸盐)与卤代胂的串联金属转移(Sn→Au→As)得到直接访问一系列新的胂碳炔配合物,L n M≡CAsR 2,包括不寻常的杂环 phenarsazininyl 和 arsolyl 例子。
