| Abstract: | Methylation of SiH4, MeSiH3, Si2H6, GeH4 and B2H6, but not of PH3 or AsH3, was observed during reaction (230–324°C) with GaMe3. The products from the SiH4 and Si2H6 reactions were MeSiH3, Me2SiH2 and Me3SiH. The GeH4-derived products were similar, with Me4Ge also being formed. The only methylated products from B2H6 was BMe3. The silane reactions were surface-catalyzed (presumably by surface hydroxyl groups), while those of GeH4 and B2H6 may have occurred via gas-phase free radical processes. |
