 Title    Übergangsmetall-Garben-Komplexe, CXXI [1] Fluorcarbenkomplexe des Mangans Transition Metal Car bene Complexes, CXXI [1] Fluorocarbene Complexes of Manganese  
 Abstract    The reaction between CH3CsH4Mn(C0)3 and LiN(C2Hs)2 and subsequent alkylation with [(C 2 H 5)30]BF4 affords CH 3 C5H4(CO)2MnC(OC2H5)N(C2H5)2. This carbene complex reacts with borontrihalides BX 3 (X = F, Cl) to yield [CH 3 C5H4(C0)2MnCN(C2H 5)2]BX 4 . Ad-dition of [(C 4 H 9) 4 N]F to this cationic carbyne complex results in the formation of CH3C5H4(CO)2MnC(F)N(C2H5) 2 . In the same way C 5 H5(C0)2MnC(F)C 6 H5 is prepared from [CsH^CO^MnCCeHslSbClß. Fluoride addition can be reversed by reaction of the latter carbene complex with BF3 to give [CsH5(CO)2MnCC6H5]BF4. In the X-ray structure of C5H5(C0)2MnC(F)C6H5 unusual bonding parameters are found, which are consistent with the easy cleavage of the C(carbene)-F bond.
