General description

Silicon tetraacetate is an alternative to silicon hydride and alkoxide for low-temperature SiO2 production.[1] Silicon tetraacetate reacts with ethanol in absence of water to form silica gel and ethyl acetate.[2] Silicon tetraacetate is reported as a sol-gel precursor.[2]

Application

Silicon tetraacetate may be used in the preparation of silicon dioxide thin films by a direct photochemical vapor deposition method.[1] It may be used as starting material in the synthesis of silicon complexes with monofunctional bidentate Schiff bases.[3]
