ABSTRACT
Reaction of M(CO)6; M = Mo or W with isatin in the presence of triphenylphosphine in THF under reduced pressure gave the tricarbonyl derivatives complexes [M(CO)3(isatH)(PPh3)]. The two complexes were characterized by elemental analysis, infrared, mass and 1H NMR spectroscopy. The spectroscopic studies show that the two complexes exist in fac- and mer-isomers in solutions through exchange the CO group and PPh3. The Uv-Vis spectra of the complexes in different solvents were studied.
