Abstract

Several mono- or bis-alkynyl derivatives of general formula Pt6(μ-PBu(t)2)4(CO)4X(C[triple bond, length as m-dash]C-R), Pt6(μ-PBu(t)2)4(CO)4(C[triple bond, length as m-dash]C-R)2 or Pt6(μ-PBu(t)2)4(CO)4(C[triple bond, length as m-dash]C-R)(C[triple bond, length as m-dash]C-R') were obtained under Sonogashira type conditions. The new clusters have been characterized with microanalysis and using IR and multinuclear NMR spectroscopy. The crystal and molecular structures of Pt6(μ-PBu(t)2)4(CO)4(C[triple bond, length as m-dash]C-R)2 (R = H, C6H4-4-n-C5H11) are presented and electrochemical and spectroelectrochemical studies of some representative compounds are also reported.

摘要

在Sonogashira型反应条件下，制备得到了通式为Pt6(μ-PBu(t)2)4(CO)4X(C≡C-R)、Pt6(μ-PBu(t)2)4(CO)4(C≡C-R)2或Pt6(μ-PBu(t)2)4(CO)4(C≡C-R)(C≡C-R')的几种单炔基或双炔基衍生物。通过微量分析、红外光谱和多核核磁共振光谱对这些新型簇合物进行了表征。给出了Pt6(μ-PBu(t)2)4(CO)4(C≡C-R)2（R = H，C6H4-4-n-C5H11）的晶体和分子结构，并报道了一些代表性化合物的电化学和光谱电化学研究结果。
