| Abstract: | Chloride-bridged tungsten tricarbonylmetalates [(OC)3W(Cl)3W(CO)3]3?, obtainable in high yields from tungsten hexacarbonyl and tetraalkylammonium chlorides, with allyl halides give π-allylhalogenotungsten dicarbonyls. With phosphines reductive elimination of allylhalide yields bis- or tris-(phosphine)-tungsten-dicarbonyls L2W(PR3)2(CO)2, LW(PR3)P3(CO)2 (L = CH3CN). Substitution reactions of L with various ligands under mild conditions are described. IR and electronic spectra of more than twenty new compouonds are discussed and compared with corresponding compounds of molybdenum. |
