In the presence of a bidentate chelate containing two
convergent nitrile groups, Ru(phen)2L2+ (L =
sterically hindering aromatic diimine ligand; phen = 1,10-phenanthroline)
undergoes a photochemical reaction leading to quantitative replacement of
the diimine by the bis-nitrile ligand; the reverse reaction takes place
upon heating, also quantitatively.
Ru(phen)2L2+ (L = 具有立体阻碍作用的芳香族二亚胺配体;phen = 1,10-菲罗啉)在含有两个聚合腈基的双齿螯合物存在下发生光化学反应,导致二亚胺被双腈配体定量取代;加热后发生反向反应,也是定量取代。
