General description
Potassium methoxide is a basic nucleophile used in the dehalogenation of arylhalides.
Application
Potassium methoxide can be used:
- As a methoxylating agent for methoxylation of bromo- and mesyloxyalkanes in the presence of an ionic liquid [bmim][BF4].
- As a catalyst for the synthesis of dimethyl carbonate and methyl formate.
- As a catalyst for the transesterification of sunflower oil for the production of biodiesel.
