摘要
通过非对称型双-μ-烃硫六羰基二铁同三苯膦的反应合成了十四个新的三苯膦Fe-S原子簇络合物,讨论了三苯膦对络合物C≡O的IR和S—烃基的~1HNMR的影响,确定了三苯膦在络合物中的空间取向。
Fourteen new Pph_(3)-substituted Fc-S clusters with general formula(μ-RS)(μ-R’S)Fe_(2)(CO)_(5)Pph_(3)have been synthesized by the reaction of unsymmetrical type of bis(μ-alkylthio)-hexacarbonyldiirons with triphenylphosphinc.Their m.p.,IR,1HNMR and C/H analysis have been performed.Based on the analysis of the influence of Pph_(3)on vco andδ-alkyl,the spacial orientation of Pph_(3)in these clusters has also been established.
