| Reaktionen von Acetylenkomplexen des Wolfram(IV) mit Tetrachloro-l,2-benzochinon Reactions of Acetylene Complexes of Tungsten(IV) with Tetrachloro-1,2-benzoquinone  | | | | Abstract
| Acetylene complexes of tungsten(IV) of the type [WC14(RCSCR)]2 (R = halogene, phenyl) react with tetrachloro-1,2-benzoquinone to give monomeric tungsten(VI) chelate complexes WC12(02C6C14)2 and W(02C6C14)3, respectively. The complexes have been characterized by their IR and mass spectra. | | | |

The reactivity of the PH-groups can be employed for the synthesis of tridentate NPN-hvbrid donors. [2-C5H4N —CH 2 —CH 2 ] 2 PR (R = H. Ph). The phosphanes 2-C 5 H 4 N-[CH 2 ]"-PRH behave as monodentate ligands in transition metal complexes and form labile chelate ring systems. They may bridge metal-metal bonds to form seven membered ring systems, e.g. Mo 2 PC 3 N. The coordi-nation of the N-donor of the ligands 2-C 5 H 4 N — [CH,]"-PRH to a transition metal atom is indi-cated by a lowfield shift and a small 3I P-13 C-splitting of the l3 C{ ! H} NMR signal of carbon atom 6 in the pyridin ring system. | | | |
