Nonfiction: Diethylzinc. It was discovered by Edward Frankland, who synthesized diethylzinc and dimethylzinc by the reaction of ethyl iodide and methyl iodide with metallic zinc.
The theoretical deductions Frankland drew from considering these bodies were even more interesting and important than the bodies themselves. Perceiving a molecular isonomy between them and the inorganic compounds of the metals from which they may be formed, Frankland saw their true molecular type in the oxygen, sulfur or chlorine compounds of those metals, from which he held them to be derived by the substitution of an organic group for the oxygen, sulfur, &c. In this way they enabled him to overthrow the theory of conjugate compounds, and they further led him in 1852 to publish the conception that the atoms of each elementary substance have a definite saturation capacity, so that they can only combine with a certain limited number of the atoms of other elements. The theory of valency thus founded has dominated the subsequent development of chemical doctrine, and forms the groundwork upon which the fabric of modern structural chemistry reposes.
