Microwave-Assisted Synthesis of Functionalized Shvo-Type Complexes

A simple and expeditious microwave-assisted procedure for the synthesis of a variety of Shvo-type ruthenium complexes has been developed by reacting Ru3(CO)12 with variously functionalized tetraarylcyclopentadienones under microwave irradiation in MeOH. Ligand precursors have also been prepared under microwave heating by a bis-aldol condensation of 1,3-diphenylacetone with variously functionalized aromatic diketones. All the reactions were very fast and clean, leading to good yields and purities.

本研究开发了一种简便快捷的微波辅助合成方法，用于制备多种肖夫型钌配合物：将十二羰基三钌（Ru₃(CO)₁₂）与不同官能化的四芳基环戊二烯酮置于甲醇（MeOH）中，在微波辐射条件下进行反应。此外，本研究还通过微波加热，以1,3-二苯基丙酮与不同官能化的芳基二酮发生双羟醛缩合反应，制备了配体前驱体。所有反应均快速且洁净，产物收率与纯度俱佳。
