Photochemical reaction of W(CO)6 with SnCl4 III. Synthesis of some novel seven-coordinate tungsten(II) complexes [WCl(SnCl3)(CO)3L2] (L≡N− and P-donor ligands)
摘要:
The photochemical reaction of W(CO)(6) with SnCl4 gives the oxidation addition product [(CO)(4)W(mu-Cl)(3)W(SnCl3)(CO)(3)] (1). Compound 1 reacts with ligands L=CH3CN, bipy, PPh(3) or dppe to give the seven-coordinated species [WCl2(CO)(3)L(2)] and [WCl(SnCl3)(CO)(3)L(2)]. These W-(II) compounds can be prepared in a one-pot two-step manner, without isolating the intermediate[(CO)(4)W(mu-Cl)(3)W(SnCl3)(CO)(3)] (1).
