| 摘 要： | The transmetallation reaction of 4 Schiff base type arylmercury compoundswith metallic tin has been carried out in refluxing xylene.It was found that thereaction proceeds in the same manner as that of chloro2-(phenylazo)phenyl]mercury(Ⅱ)to give dichlorobisaryltin(Ⅳ).The ~1H NMR spectra of the products provide evidence forthe presence of N→Sn intramolecular coordination.The formation ofdichlorobisaryltin(Ⅳ)as a unique product probably arises from the N→Sn intramolecularcoordination which results in the increasing of the stability of the molecule.
