| | Trimethyloxonium Tetrafluoroborate Usage And Synthesis |
| Chemical Properties | This substance is a white to off-white crystals that is prone to water sensitivity and displays a level of hygroscopicity. | | Uses | Trimethyloxonium Tetrafluoroborate is a trialkylated oxonium used as a methylation agent in organic synthesis. | | Uses | Reagent for the methylation of hydroxyl groups recently used in a complex, multistep synthesis directed towards spirastrellolide, a marine natural product. | | Uses | Trimethyloxonium tetrafluoroborate act as a avmethylating agent and activates C-X multiple bonds. It is involved in the esterification of polyfunctional carboxylic acids. It acts as a catalyst in the polymerization of cyclic sulfides and ethers. Further, it is used in Beckmann rearrangement of oximes. | | Health Hazard | Trimethyloxonium Tetrafluoroborate is a potent alkylating agent, with its non-volatile nature reducing associated hazards. Nevertheless, it produces strong acids upon contact with water, so it is important to exercise caution and prevent water contact during its application. |
