It participates in the TiO2-assisted photooxidation of substituted benzyltrimethylsilanes in acetonitrile. Diarylethanes were obtained in 50-74% yields.[1] Application Silver sulfate may be employed in the preparation of the following: - Iodination reagent in combination with iodine for the synthesis of iododerivatives.[2] - Silver sulfate reagent, which is required for the determination of Chemical Oxygen Demand (COD).[3] |
