Novel derivative chemistry of silatranes

Abstract

In order to synthesize heteropolynuclear comounds containing bonding interaction between the silicon of silatrane and M (M: transition metal or main group element), a series of reactions such as HCl elimination, salt elimination reaction, and oxidative addition reaction has been utilized. The reaction of $Tl_2C_2B_9H_{11}$ with 1-bromosilatrane in tetrahydrofuran gives tetrasilatranyloxysilane having novel structure, which is characterized by a single-crystal x-ray diffraction study. The reaction of $SnBr_2$ with 1-bromosilatrane in acetonitrile gives the mixture of yellow and white solid, which was isolated and characterized by $^1H-NMR$, $^{29}Si-NMR$, $^{119}Sn-NMR$ and Mass spectroscopy. The yellow compound was characterized as tribromo-1 silatranyltin which had Si-Sn bonding interaction.
