In the laboratory, THF is a popular solvent when its water miscibility is not an issue. It is more basic than diethyl ether and forms stronger complexes with Li +, Mg 2+, and boranes. It is a popular solvent for hydroboration reactions and for organometallic compounds such as organolithium and Grignard reagents. See more Tetrahydrofuran (THF), or oxolane, is an organic compound with the formula (CH2)4O. The compound is classified as heterocyclic compound, specifically a cyclic ether. It is a colorless, water-miscible organic … See more Polymerization In the presence of strong acids, THF converts to a linear polymer called poly(tetramethylene ether) glycol See more THF is a relatively acutely nontoxic solvent, with the median lethal dose (LD50) comparable to that for acetone. However, chronic exposure is suspected of causing cancer.

The most widely used industrial process involves the acid-catalyzed … See more THF is a Lewis base that bonds to a variety of Lewis acids such as I2, phenols, triethylaluminum and bis(hexafluoroacetylacetonato)copper(II). THF has been classified in the ECW model and it has been shown that there is no one order of base … See more Tetrahydrofurans The tetrahydrofuran ring is found in diverse natural products including lignans, acetogenins, and polyketide natural products. Diverse methodology has been developed for the synthesis of substituted THFs. See more WebSn1 reactions depend on the stability of the cation formed when the Leaving group had left. So, since tertiary carbocations are most stable of the three will undergo Sn1 reaction easily. Order: Tertiary > Secondary > Primary Sn2 reactions depend on the fastness of the leaving group. The fastness depends on the Leaving group.
