五羰基钌是一种有机钌化合物,化学式为Ru(CO)5。它是无色对光敏感的液体,在室温放置时迅速脱去一氧化碳。它可用于金属羰基配合物的合成研究。[1]

制备及性质

[编辑]

五羰基钌最初由钌化合物在还原剂的存在下羰基化得到,[2]后来有了十二羰基三钌光化学反应制法:[1]

Ru3(CO)12 + 3 CO ⇌ 3 Ru(CO)5

它的红外谱的νCO在2038和2003 cm−1处(己烷溶液)有两处强峰。[1]

它和八羰基二钴在一氧化碳气氛中反应,再经盐酸酸化,可以得到红色的Co3RuH(CO)12[3]

4 Ru(CO)5 + 7 Co2(CO)8 → 2 Co*[Co3Rh(CO)12]2 + 28 CO
Co*[Co3Rh(CO)12]2 + 2 HCl → 2 Co3RuH(CO)12 + CoCl2 (其中Co*表示溶剂化的Co(II)离子)

它和Pt(COD)2反应,可以得到紫色的Pt2Ru4(CO)18,这种物质可以进一步和氢气反应,得到Pt3Ru6(CO)213-H)(μ-H)3[4]

4 Ru(CO)5 + 2 Pt(COD)2 → Pt2Ru4(CO)18 + 2 CO + 4 COD (COD为1,5-环辛二烯
3 Pt2Ru4(CO)18 + 4 H2 → 2Pt3Ru6(CO)21H4 + 12 CO
