Reactivity of Phosphorus Pentahalides with Transition Metal Carbonyls. III. Reactivity of PBr5 with Hexacarbonyls of Molybdenum and TungstenPBr5 reacts with M(CO)6 (M = Mo, W) already at room temperature in CH3CN as solvent. Independend on the reaction condition WBr4(CH3CN)2 was obtained in the reaction of PBr5 with W(CO)6. In the case of Mo(CO)6 the complexes MoBr3(CH3CN)3 and MoBr4(CH3CN)2, respectively, were isolated depending on the amount of PBr5 and the reaction temperature. The structure of the products is discussed on the basis of the IR spectra and of magnetic moments.
Notes:
PBr5 reagiert mit M(CO)6 (M = Mo, W) in Acetonitril bereits bei Raumtemperatur. Für W(CO)6 wird unabhängig von den Reaktionsbedingungen stets WBr4(CH3CN)2 erhalten. Für Mo(CO)6 wird in Abhängigkeit von der Reaktionsführung, der Menge an PBr5 und der Reaktionstemperatur MoBr3(CH3CN)3 bzw. MoBr4(CH3CN)2 gebildet. Die Struktur der erhaltenen Produkte wird anhand der IR-Spektren und der magnetischen Messungen diskutiert.
