Tetraethylammonium iodide

Tetraethylammonium iodide [68-05-3] M 257.2, m 302 , >300 (dec). Crystd from acetone/MeOH, EtOH/water, dimethylacetamide or ethyl acetate/EtOH (19 1). Dried under vacuum at 50° and stored over P2OS. [Pg.359]

Chloro-3,4-dimethylthiazolium tetrafluoroborate with [Mn(CO)5] gives the carbene complex 19 (74JCS(D)760). The product reacts with tetraethylammonium iodide to give the cM-neutral complex 20. [Pg.194]

It is well known that the surrounding solvent environment plays a crucial role in a chemical reaction. For example, the formation of tetraethylammonium iodide has been studied in many nonpolar and polar solvents. It is found that the rate of the reaction is quite sensitive to the solvent. From the least polar (hexane) to the most polar (nitrobenzene) solvent, the rate constant increases by 2700 times [1]. The polar transition state of this reaction is stabilized in a high dielectric constant medium. Since the... [Pg.379]

Bis (tetraethylammonium) tetraiodomanganate(II). It is difficult to crystallize this compound from ethanol because it is quite soluble in the hot solvent and on cooling the solution tetraethylammonium iodide is obtained. However, it is possible to obtain the complex if excess manga-... [Pg.137]

Influence of Solvent on Ion Conductance.—In the course of his investigation of the conductance of tetraethylammonium iodide in various solvents, Walden (1906) noted that the product of the equivalent conductance at infinite dilution and the viscosity of the solvent was approxi-... [Pg.63]

Pyrazolines have been investigated polarographically in a 2 2 1 mixture of DMF, benzene, and methanol with tetraethylammonium iodide as electrolyte. The polarographic data... [Pg.694]

A/-Alkylation of benzylhydroxylamine by a primary alkyl bromide proceeded smoothly at room temperature. HMPA is the solvent of choice and addition of tetraethylammonium iodide facilitates the reaction. Dehydration of the resulting V-alkylhydroxylamines and subsequent acid hydrolysis gave the corresponding primary amines (Scheme 45). ... [Pg.83]
