摘要
The reaction between (C6F5NHCH2CH2)(2)NH and methyl iodide in the presence of base leads to (C6F5NHCH2CH2)(2)NMe (H-2[ArFNMe]) in good yield. Reactions between H-2[ArFNMe] and MCl4 (M = Mo or W) in the presence of NEt3 yield pseudooctahedral paramagnetic compounds of the type [Et3NH]{[ArFNMe]MCl3}. The reaction between 3 equiv of MeMgCl and [Et3NH]-{[ArFNMe]MoCl3} produced paramagnetic trigonal bipyramidal [ArFNMe]MoMe2. The reaction between H-2[ArFNMe] and Mo(NMe2)(4) produced paramagnetic seven-coordinate [(C6F4(NMe2)NCH2CH2)(2)NMe]MoF2 instead of five-coordinate [(C6F5NCH2CH2)(2)NMe]Mo (NMe2)(2), while the reaction between H-2[ArFNMe] [NEt4](2)[Re(O)-Cl-5] and NEt3 produced diamagnetic trigonal bypramidal [ArFNMe]Re(O)CI. X-ray studies confirmed the structures of [Et3NH]{[ArFNMe]MoCl3}, [ArFNMe]MoMe2, [(C6F4(NMe2)NCH2CH2)(2)NMe]MoF2, and [ArFNMe]Re(O)Cl.
