摘要

本文描述了与苯并噻唑啉-2-吡啶配体的金(I)配合物的制备。这些以前未报道的配合物可以用所谓的弱碱路线从相应的苯并噻唑前体中方便地制备出来，并且已经进行了光谱和结构表征。结合结构分析和计算分析，证实了苯并噻唑啉-2-吡啶配体与传统的（苯并）咪唑啉基NHCs相比具有更强的接π特性。所得到的配合物相当稳定，可用氢化钾控制还原作为配体稳定金纳米颗粒的前驱体。该反应产生3nm大小的金纳米颗粒，在溶液和固体状态下都是稳定的，并且可以通过光谱（NMR, UV-Vis）和透射电子显微镜（TEM）进行表征。

Benzothiazolin-2-ylidene gold(I) complexes as precursors for gold nanoparticles

The preparation of gold(I) complexes with benzothiazolin-2-ylidene ligands is described herein. These previously unreported complexes can be conveniently prepared from the corresponding benzothiazolium precursors using the so-called weak base route and have been spectroscopically and structurally characterized. Combined structural and computational analysis confirms enhanced π-accepting character of benzothiazolin-2-ylidine ligands in comparison with conventional (benz)imidazolin-based NHCs. The obtained complexes are reasonably stable and have been used as precursors for ligand-stabilized gold nanoparticles by controlled reduction with potassium hydride. The reaction produces 3 nm sized gold nanoparticles that are stable in solution as well as in the solid state and can be characterized both spectroscopically (NMR, UV–Vis) and by transmission electron microscopy (TEM).

期刊介绍： The Journal of Organometallic Chemistry targets original papers dealing with theoretical aspects, structural chemistry, synthesis, physical and chemical properties (including reaction mechanisms), and practical applications of organometallic compounds. Organometallic compounds are defined as compounds that contain metal - carbon bonds. The term metal includes all alkali and alkaline earth metals, all transition metals and the lanthanides and actinides in the Periodic Table. Metalloids including the elements in Group 13 and the heavier members of the Groups 14 - 16 are also included. The term chemistry includes syntheses, characterizations and reaction chemistry of all such compounds. Research reports based on use of organometallic complexes in bioorganometallic chemistry, medicine, material sciences, homogeneous catalysis and energy conversion are also welcome. The scope of the journal has been enlarged to encompass important research on organometallic complexes in bioorganometallic chemistry and material sciences, and of heavier main group elements in organometallic chemistry. The journal also publishes review articles, short communications and notes.
