Übergangsmetall-Carbin-Komplexe, L Darstellung und nukleophile Substitution von Tetracarbonyl(organylcarbin)tetrafluoroborato-metall-Komplexen /Transition Metal Carbyne Complexes, L Preparation and Nucleophilic Substitution of Tetracarbonyl(organylcarbyne)tetrafluoroborato Metal Complexes

Abstract

Pentacarbonyl[methoxy(organyl)carbene]chromium complexes react in boron trifluoride dimethyletherate in the presence of BF3 to form tetracarbonyl(organylcarbyne)-tetrafluoroborato complexes of chromium. In the analogous tungsten complex BF4(CO)4WCC6H5 the BF4--ligand is displaced by nucleophilic reagents. With As(C6H5)3 and t-C4H9NC the cationic derivatives [As(C6H5)3(CO)4WCC6H5][BF4]as well as [t-C4H9NC(CO)4WCC6H5][BF4]are obtained.
