The oxidative addition reaction has been employed to synthesize heteropolynuclear compounds containing Si-M bonding interaction between the silicon atom of silatrane, pentacoordinate silicon derivative with transannular Si-N dative bond, and the main group element. The reaction of SnBr2 with 1-bromosilatrane(1a) in acetonitrile gives the mixture of yellow(2a) and white(2b) solids which were isolated and charaterized by 1H-NMR, 29Si-NMR, 119Sn-NMR and Mass spectroscopy. The yellow compound was characterized as 1-tribromotinsilatrane which had Si-Sn bonding interaction. The reaction of SnBr2 with 1-bromo-3,7,10-trimethylsilatrane(1b) in methanol gives the Sn(Ⅳ) complex, N[CH2CH(CH3)O]3SiSnBr3(CH3OH)2(3), which was characterized by various means.
