| Abstract: | Tungsten Complexes of Diphosphanylacetylenes Diphosphanylacetylenes, R2P? C?C? PR2 R?N(C2H5)2 ( 1 ), N(CH2)2]2O ( 2 ), OCH3 ( 3 )] and W(CO)5 · tetrahydrofurane form the mononuclear complexes R2P? C?C? PR2 · W(CO)5 R?N(C2H5)2 ( 1a ), N(CH2)2]2O ( 2a )], the dinuclear complexes (CO)5W? PR2? C?C? PR2? W(CO)5 R?N(C2H5)2 ( 1b ), N(CH2)2]2O ( 2b ), OCH3 ( 3b )], and the trinuclear complex (CO)5W? PR2? C?C? PR2? W(CO)4? PR2? C?C? PR2? W(CO)5 R?N(C2H5)2 ( 4 )]. The new compounds are characterized by their NMR, mass, and IR spectra. The results of an X-ray structural analysis of 4 are reported. |
