2-Methyltetrahydrofuran (2-MTHF), a 2-methyl substituted tetrahdrofuran, is a biomass derived solvent. It is a potential greener solvent alternative for organic synthesis. It shows resistance to reduction by lithium making it a promising candidate as electrolytes in lithium batteries. Its polarity and Lewis base strength is intermediate between tetrahydrofuran (THF) and diethyl ether. The ring opening reaction of 2-MTHF has been studied using acid chloride and iodide to form secondary chlorides and primary iodides respectively. On long term storage, tetrahydrofuran forms organic peroxides. This process can be suppressed by adding butylated hydroxytoluene (BHT) as a stabilizer. BHT removes the free radicals required for the peroxide formation.

Zastosowanie

2-Methyltetrahydrofuran may be used as solvent for phosphatidylserine synthesis.
It may be used as an alternative solvent to:

• DMSO (dimethyl sulfoxide) or MTBE (methyl tertiary butyl ether) in the C-C bond forming reactions catalyzed by lyase enzyme.
• THF in the reaction between Grignard reagents and carbonyl compounds.
• Methylene chloride in some biphase reactions.
