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.
Highlights
Isatin (2,3-dihydroindole-2, 3-dione) is a versatile leadmolecule for designing potential bioactiveagents, and its derivatives were reported to possess broad-spectrum antiviral activity [1, 2]
We report the synthesis and characterization of molybdenum and tungsten complexes of isatin in the presence of PPh3
Taking into account the electronic spectra the combination of a reducing metal and an acceptor ligand generates a metal-to-ligand charge transfer (MLCT) excited state which may appear in absorption and emission [5, 6]
