4 Et 2 O·BF 3 + 2 Et 2 O + 3 C 2 H 3 OCH 2 Cl → 3 [Et 3 O] + [BF 4] − + B(OCH(CH 2 Cl)CH 2 OEt) 3. where the Et stands for ethyl. The trimethyloxonium salt is available from dimethyl ether via an analogous route. [6] These salts do not have long shelf-lives at room temperature. They degrade by hydrolysis: [Et 3 O] + [BF 4] − + H 2 O → ...
Methyl benzoate is an organic compound. It is an ester with the chemical formula C 6 H 5 COOCH 3, sometimes abbreviated as PhCO 2 Me, where Ph and Me are phenyl and methyl, respectively. Its structure is C 6 H 5 −C(=O)−O−CH 3. It is a colorless liquid that is poorly soluble in water, but miscible with organic solvents.
[me 3 o] + [bf 4] − + h 2 o → me 2 o + meoh + h + [bf 4] − Trimethyloxonium tetrafluoroborate is generally ranked as the strongest commercially available reagent for electrophilic methylation , [ 1 ] being stronger than methyl sulfonate esters, including methyl triflate and methyl fluorosulfonate ("magic methyl").

The quantity used for the curing of UP resins is about 1-2%. [2] A disadvantage, particularly in the production of polymers for applications in the food or cosmetics sector, is the possible formation of benzene as a decomposition product which can diffuse out of the polymer (for example, an LDPE packaging film).
