Web22 Nov 2024 · Abstract Different substituents on the B atom make NH 3 BH 2 R react with THFBH 3 in different ways. With R = Me or Ph, intermolecular NH 3 and THF exchange occurs and B-substituted µ -aminodiborane forms. With R = Cl, a reversible intermolecular chloride–hydride exchange takes place. Abstract WebEthyl ether or THF are essential for Grignard reagent formation.

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 liquid with low viscosity. It is mainly used as a precursor to polymers. Being polar and having a wide … See more About 200,000 tonnes of tetrahydrofuran are produced annually. The most widely used industrial process involves the acid-catalyzed dehydration of 1,4-butanediol. Ashland/ISP is one of the biggest producers of this … 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 … 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 Polymerization In the presence of strong acids, THF converts to a linear polymer called poly(tetramethylene ether) glycol (PTMEG), also known as … See more THF is a relatively acutely nontoxic solvent, with the median lethal dose (LD50) comparable to that for acetone.
