Photolysis of tungsten hexacarbonyl with bidentate ligands. Characterization and reaction kinetics of a W(CO)5L intermediate by diode-array electronic absorption spectroscopy
Abstract
Electronic absorption spectra of a monodentate W(CO)5L intermediate have been recorded during the photoinitiated reaction of W(CO)5L with L = 1,4-diazabutadiene and 2,2′-bipyridine; the W(CO)5L species subsequently extrudes CO in a first order kinetic process to form W(CO)4L.
