Isomeric olefin tetracarbonyl complexes of tungsten(I): An infrared spectroelectrochemical study at low temperatures
In situ electrolysis within an optically transparent thin-layer electrochemical (OTTLE) cell was applied at 293-243 K in combination with FTIR spectroscopy to monitor spectral changes in the carbonyl stretching region accompanying oxidation of four tetrac

Photochemical synthesis and thermal interconversion of mer- and fac-W(CO)3(P(OMe)3)(η4-1,5-cyclooctadiene)
Both fac and mer isomers of W(CO)3(P(OMe)3)(η4-1,5-cyclooctadiene) are formed in a photolysis reaction. They readily interconvert thermally, with the fac isomer favored by a ca. 2:1 ratio.

DINUCLEAR μ-ALKYLIDENE COMPLEXES OF TUNGSTEN FROM MONONUCLEAR, HETEROATOM-SUBSTITUTED VINYL-ALKYLIDENE COMPLEXES OF THIS METAL
A general synthesis of homodinuclear μ-alkylidene complexes of tungsten, starting from Fischer type alkylidene complexes of tungsten is outlined.Thus the vinyl-alkylidene complexes (CO)5W=C(OMe)CHCHR react with (CO)5W=CPh2, as a source of coordinatively unsaturated w(CO)4, to give the dinuclear complexes W2(CO)9(OMe)CHCHR, and the complex (CO)5W=C(OMe)CHCH2 reacts slowly in hydrocarbon solution, in the absence of (CO)5W=CPh2, to give a dinuclear complex W2(CO)19C(OMe)CHCH2 in which the two metal centers are not bound together: this product is the result of coordination of the double bond of the starting material to a W(CO)5 species.
