19 de jun. de 2024 · Clearly, we can see that the intermediate compound formed is R-Zn-I. During the reaction, free radical is formed. The reaction was discovered by Edward Frankland in July 1849, a young chemist in England. This reaction is now regarded as a key event in organic and organometallic chemistry. Symmetric alkanes can be prepared by using this reaction.

Hace 5 días · The first organotin compound to be reported was diethyltin diiodide ((C 2 H 5) 2 SnI 2), reported by Edward Frankland in 1849. Most organotin compounds are colorless liquids or solids that are stable to air and water. They adopt tetrahedral geometry. Tetraalkyl- and tetraaryltin compounds can be prepared using Grignard reagents: SnCl 4 + 4 ...
