CAS 420-37-1: Trimethyloxonium tetrafluoroborate

Description:Trimethyloxonium tetrafluoroborate is a chemical compound with the formula [(CH₃)₃O]BF₄. It is characterized as a stable, colorless, and hygroscopic solid that serves as a strong methylating agent. The compound features a trimethyloxonium cation, which is a positively charged species derived from trimethylamine and methanol, and a tetrafluoroborate anion, known for its non-coordinating properties. Trimethyloxonium tetrafluoroborate is highly soluble in polar solvents, such as acetonitrile and methanol, making it useful in various organic synthesis applications, particularly in the methylation of nucleophiles. Its reactivity is attributed to the electrophilic nature of the trimethyloxonium ion, which readily donates a methyl group to nucleophiles. However, due to its strong reactivity, it must be handled with care, as it can react violently with water and other nucleophiles. Overall, this compound is valuable in synthetic organic chemistry for its ability to introduce methyl groups into various substrates.
