Frankland's original synthesis of diethylzinc involves the reaction of ethyl iodide with zinc metal. The zinc must be activated to facilitate this redox reaction. One of such activated form of zinc employed by Frankland is zinc-copper couple. [5]
Diethylzinc (C 2 H 5) 2 Zn, 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.
After his return to England Frankland achieved the synthesis of diethylzinc and dimethylzinc by the reaction of ethyl iodide and methyl iodide with metallic zinc. [17] The theoretical deductions Frankland drew from considering these bodies were even more interesting and important than the bodies themselves.
Zinc is an essential trace element for humans, [8] [9] ... synthesis, and chemical reactions. Many organozinc compounds are commercially important. ... The Frankland ...
An early step in main group organometallic chemistry (if one considers Zn to be a main group element) involved the synthesis of organozinc compounds diethyl zinc by Frankland. [5] Tetraethyllead is the focus of an infamous episode involving main group organometallic compounds.
Dimethylzinc was first prepared by Edward Frankland during his work with Robert Bunsen in 1849 at the University of Marburg. After heating a mixture of zinc and methyl iodide in an airtight vessel, a flame burst out when the seal was broken. [ 5 ]

Zinc compounds are chemical compounds containing the element zinc which is a member of the group 12 of the periodic table. The oxidation state of zinc in most compounds is the group oxidation state of +2. Zinc may be classified as a post-transition main group element with zinc(II). Zinc compounds are noteworthy for their nondescript appearance ...
