RuCl2(POMe)2 (POMe = diphenyl(2-methoxyphenyl)phosphine) 的製備與特性都已經被完整的報導過了。然而,把RuCl2(POMe)2在RCN (R = Me, Et) 溶劑下加熱迴流,就會導致兩個CH3Cl的離去生成化合物Ru(RCN)2(PO)2 (R = Me(1), Et(3)),則從未有人研究過。如果在反應裡加入KPF6 或者 KBF4 就會得到額外的產物[Ru(RCN)2(PO)(POMe)]+ (R = Me(2), Et(4));依反應溶劑的選擇而定。化合物2和4的去烷化反應同時包含CH3Cl和[CH3(POMe)]+ 的路徑。經由NMR和ESI-mass光譜的追蹤可以幫助我們清楚了解釕錯合物的去烷化路徑。化合物1、2和3都成功地解出X-ray結構。
The preparation and characterization of RuCl2(POMe)2 (POMe = diphenyl(2-methoxyphenyl)phosphine) was reported. However, the reactions of RuCl2(POMe)2 with refluxing RCN (R = Me, Et) led to loss of CH3Cl to give Ru(RCN)2(PO)2 (R = Me(1), Et(3)), which are never reported. Adding KPF6 or KBF4 in the reactions will give additional products [Ru(RCN)2(PO)(POMe)]+ (R = Me(2), Et(4)) according to the solvent selection. Complexes 2 and 4 were observed the dealkylating via loss of CH3Cl or [CH3(POMe)]+ pathways. The [CH3(POMe)]+ pathway needs excess POMe which may come from the thermal decomposition of [RuCl(POMe)2(RCN)]+. The NMR and ESI-mass monitoring spectra also help us to understand the Ru complexes dealkylation pathway. The structures of 1, 2, and 3 were confirmed by X-ray analyses.
