 Title    Übergangsmetall-Carbin-Komplexe, L [1] Darstellung und nukleophile Substitution von Tetracarbonyl(organylcarbin)tetrafluoroborato-metall-Komplexen Transition Metal Carbyne Complexes, L [1] Preparation and Nucleophilic Substitution of Tetracarbonyl(organylcarbyne)tetrafluoroborato Metal Complexes  
 Abstract    Pentacarbonyl[methoxy(organyl)carbene]chromium complexes react in boron tri-fluoride dimethyletherate in the presence of BF3 to form tetracarbonyl(organylcarbyne)-tetrafluoroborato complexes of chromium. In the analogous tungsten complex BF4(CO)4WCC6Hs the BF4--ligand is displaced by nucleophilic reagents. With As(C6H5)3 and <-C4H9NC the cationic derivatives [As(C6H5)3(CO)4WCC6H5][BF4] as well as [<-C4H9NC(CO)4WCC6H5][BF4] are obtained. Die Umsetzung von Pentacarbonyl[alkoxy(orga-nyl)carben]-Komplexen mit Bortrihalogeniden BX3 in Pentan bei tiefen Temperaturen führt für X = Cl, Br, I zu den in großer Vielfalt dargestellten trans-Halogeno(tetracarbonyl)carbin-Komplexen desTyps
