Trimethyloxonium Tetrafluoroborate Usage And Synthesis
Chemical PropertiesThis substance is a white to off-white crystals that is prone to water sensitivity and displays a level of hygroscopicity.
UsesTrimethyloxonium Tetrafluoroborate is a trialkylated oxonium used as a methylation agent in organic synthesis.
UsesTrimethyloxonium 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.
UsesReagent for the methylation of hydroxyl groups recently used in a complex, multistep synthesis directed towards spirastrellolide, a marine natural product.
Health HazardTrimethyloxonium 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.
