WebTo a solution of diethylzinc (ca. 1mol/L in hexane, 2.9 mL, 2.9 mmol) and tridecafluorohexyl iodide (0.92 mL, 4.2 mmol) in DMPU (1.2 mL) was added ethyl 2-Iodobenzoate (500 mg, 1.9 mmol) and copper(I) iodide (37 mg, 0.20 mmol) and the reaction mixture was stirred under nitrogen at 90 °C for 16 hours. The reaction was quenched with 4 mol/L HCl ... Diethylzinc (C2H5)2Zn, or DEZ, is a highly pyrophoric and reactive organozinc compound consisting of a zinc center bound to two ethyl groups. This colourless liquid is an important reagent in organic chemistry. It is available commercially as a solution in hexanes, heptane, or toluene, or as a pure liquid. See more Edward Frankland first reported the compound in 1848 from zinc and ethyl iodide, the first organozinc compound discovered. He improved the synthesis by using diethyl mercury as starting material. The contemporary … See more The compound crystallizes in a tetragonal body-centered unit cell of space group symmetry I41md. In the solid-state diethylzinc shows nearly linear Zn centres. The Zn-C bonds measure 194.8(5) pm, while the C-Zn-C angle is slightly bent with 176.2(4)°. The … See more • Demonstration of the ignition of diethylzinc in air Video - University of Nottingham See more Despite its highly pyrophoric nature, diethylzinc is an important chemical reagent. It is used in organic synthesis as a source of the ethyl carbanion in addition reactions See more Diethylzinc decomposes violently on contact with water and can spontaneously ignite upon contact with air. It should therefore be handled using inert atmosphere techniques See more secure dog field chichester
