Descrição geral
Trimethyloxonium tetrafluoroborate can be used as a methylating agent for the methylation of hydroxyl/carboxyl functional groups. It is capable of methylating polyfunctional carboxylic acids. It is also used as a catalyst for the polymerization of cyclic sulfides and ethers.
Aplicação
Reagent for the methylation of hydroxyl groups recently used in a complex, multistep synthesis directed towards spirastrellolide, a marine natural product.
