Abstract: The monolithio compound of N,N-dimethylaminomethylferrocene reacted with tribenzyltin chloride and dibenzyldichlorotin to form 2-(tribenzyltin)dimethylaminomethylferrocene(Ⅰ) and dibenzyl bis(2-dimethylaminomethylferrocenyl)tin(Ⅱ) respectively. While the monolithio compound of 2-(diphenylarsino)dimethylaminomethylferrocene reacted with diphenylchloroarsine to give 2,5-di(diphenyl-arsino)dimethy laminomethyl ferrocene(Ⅲ). The reaction of the dilithio compound of 2-(diphenylarsino)dimethylaminomethylferrocene with 2 mol diphenylchloroarsine gave 2,5,1'-tri(diphenylarsino)dimethyl-aminomethylferrocene(Ⅳ). The structures of the products were characterized by elemental analysis and 1H NMRspectra. The structure of compound Ⅳ was established by X-ray crystal structure determination. The crystal of Ⅳ is triclinic, space group P1, with unit cell parameters: a=1.0548(2) nm, b=1.3622(3) nm, c=1.5846(3) nm, α=95.87(3)°, β=96.54(3)°, γ=107.67(3)°, Z=2.
