摘要
关于对称型双烃硫六羰基二铁的膦、肿取代物的合成及结构已有文献报道,然而关于非对称型双烃硫六羰基二铁迄今只报道过它们的三苯基膦衍生物,而且R和R′皆为一般烃基。我们通过Michael反应,用加成-醇解等方法合成了一些含氰基、酯基或酮羰基的双烃硫六羰基二铁络合物。
Through the reaction of (μ-RS)(μ-R'S)Fe2(CO)6 A with PPh3 in boiling benzene or toluene for several hours, four mono PPh3-substituted complexes (μ-RS)(μ-R'S)Fe2(CO)5PPh3 B and three bis-PPh3-substituted complexes (μ-RS)(μ-R'S)(Fe2(CO)4(PPh3)2 C were synthesized, respectively; similarly, the reaction of A with AsPh3 in boiling toluene afforded two bis-AsPh3-substi-tuted derivatives (μ-RS)(μ-R'S)Fe2(CO)4(AsPh3)2 D.The relative reactivity of PPh3 and AsPh3 towards G=O substitution and some influences of the two ligands on IR and 1H NMR spectra of the complexes were pointed out , as well as the structural characterization of these new complexes were determined by elemental analysis, IR and 1H NMR.
