Photochemical reaction of W(CO)6 with SnCl4. III. Synthesis of some novel seven-coordinate tungsten(II) complexes (LN- and P-donor ligands)

The photochemical reaction of W(CO)6 with SnCl4 gives the oxidation addition product (1).Compound 1 reacts with ligands LCH3CN, bipy, PPh3 or dppe to give the seven-coordinated species and .These W(II) compounds can be prepared in a one-pot two-step manner, without isolating the intermediate (1).Keywords: Tungsten; Tin; Carbonyls; Seven-coordinate

The oxidative addition of SnCl4 to [W(CO)4(NCMe)(PPh3)]. The X-ray crystal structure of [WH(CO)3(NCMe)(PPh3)2]- [SnCl5·MeOH]

The oxidative addition reaction of SnCl4 with [W(CO)4(NCMe)(PPh3)] in acetonitrile gives a mixture of seven-]coordinate tungsten(II) compounds: [WCl(SnCl3)(CO)3(NCMe)(PPh3)] (1), [WCl2(CO)3(NCMe)(PPh3)] (2), [WCl(SnCl3)(CO)2(NC-Me)2(PPh3)] (3), and [WCl2(CO)2(NCMe)2(PPh3)] (4) identified by IR and NMR (1H, 13C{1H}, and 31P{1H}) studies. Treatment of [W(CO)4(NCMe)(PPh3)] with 1 equiv. of SnCl4 in CH2Cl2 solution besides compounds 1 and 2 also gives ionic species such as [HPPh3]+ and [SnCl6]2- and cationic tungsten(II) complexes. The crystal structure of one of these, [WH(CO)3(NCMe)(PPh3)2][SnCl5 ·MeOH] (5), has been established by single-crystal X-ray diffraction. The IR, 1H, 13C{1H} and 31P{1H} spectra of 5 are also described and can be correlated with the crystallographically observed geometry. A notable feature of 5 is the presence of an agostic interaction of the hydride ligand with one of the carbonyl ligands.

Tungsten(II) chlorocarbonyls as alkene metathesis, arene alkylation and alkyne polymerization catalysts

Tungsten(II) chlorocarbonyl compound obtained by photochemical oxidation of W(CO)6 with CCl4 is an active alkene metathesis catalyst, free of any organometallic component. This indicates that the initially formed alkylidene ligand must come from the alkene. In toluene solution the same tungsten(II) compound also acts as a highly active catalyst for the transformation of alkenes to alkyltoluenes. Tungsten(II) compounds, which are formed in photochemical oxidation of W(CO)6 with Group 14 tetrahalides, are extremely reactive at 25°C in phenylacetylene polymerization. The results reported here clearly demonstrate that the formation of tungsten(II) might be an important event in the creation by Lewis acids (Group 14 tetrachlorides) of the catalytic activity of tungsten(0) compounds.
