Photochemistry of [Ru(CO)5] with nitrogen heterocycles
Abstract
The photochemistry of [Ru(CO)
5
] with a series of nitrogen
heterocycles has been investigated in dichloromethane solution.
Photolysis with pyridine (py) leads to the highly unstable novel
monosubstituted complex [Ru(CO)
4
(py)]. In the case of
polydentate heterocycles, photooxidation occurs. With
2,2′-bipyridine a number of complex products are generated. With
2,2′:6,2″-terpyridine (terpy), [RuCl
3
(terpy)] is
formed. With 6-(2-thienyl)-2,2′-bipyridine (thbipy),
[RuCl
3
(thbipy)] is formed, this being soluble in donor
solvents generating [RuCl
3
(thbipy)(solv)]
(solv = solvent). The molecular structures of thbipy,
[RuCl
3
(thbipy)(dmf
)]
(dmf = dimethylformamide) and
[RuCl
3
(thbipy)(MeCN)] have been determined by single-crystal
X-ray diffraction methods.
