Abstract

Irradiation of the Keggin-type [PWO{Ru(NO)}] () polyoxometalate in CHCN results in rapid NO ligand elimination with the formation of [PWO{Ru(CHCN)}] (). This complex offers an easy entry into the Ru-based chemistry of the {PWRu} complex. Attempts to substitute N for CHCN in the presence of an NaN excess lead a variety of products: (i) [PWO{Ru(N)}] (); (ii) [PWO{Ru(NHC-CH)}] () as a click-reaction product; and (iii) [PWO{Ru(N)}] (). UV-VIS, CV, and HR-ESI-MS techniques were used for the reaction monitoring and characterization of the products.

摘要

在 CHCN 中辐照 Keggin 型 [PWO{Ru(NO)}] () 多金属氧酸盐会导致快速消除 NO 配体，形成 [PWO{Ru(CHCN)}] (). 该配合物为进入基于 Ru 的 {PWRu} 配合物化学提供了一个简单的途径。在过量 NaN 存在下尝试用 N 替代 CHCN，得到了多种产物：(i) [PWO{Ru(N)}] (); (ii) [PWO{Ru(NHC-CH)}] () 作为点击反应产物；和 (iii) [PWO{Ru(N)}] (). 采用 UV-VIS、CV 和 HR-ESI-MS 技术对反应进行监测和产物进行表征。
