General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product is a biorenewable and thus aligns with "Safer Solvents and Auxiliaries" and "Use of Renewable Feedstocks". Click here for more information.
2-Methyltetrahydrofuran (2-MTHF), a 2-methyl substituted tetrahdrofuran, is a biomass derived solvent. It is a potential greener solvent alternative for organic synthesis.[2] It shows resistance to reduction by lithium making it a promising candidate as electrolytes in lithium batteries.[3] Its polarity and Lewis base strength is intermediate between tetrahydrofuran (THF) and diethyl ether.[4] The ring opening reaction of 2-MTHF has been studied using acid chloride and iodide to form secondary chlorides and primary iodides respectively.[5] 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.

Application

2-甲基四氢呋喃是可用作磷脂酰丝氨酸合成的溶剂。[1]
可用作以下情况的替代溶剂:
• DMSO(二甲基亚砜)或 MTBE(甲基叔丁基醚)在裂解酶的催化下形成 C-C 键的反应。[6]
• 格氏试剂与羰基化合物的反应。[7]
• 二氯甲烷在某些两相反应中。[8]
