A highly efficient method for the cross-coupling of non-activated and functionalized alkyl halides and tosylates with secondary and tertiary alkyl Grignard reagents has been developed. The copper-based method is remarkably practical and general. The wide scope, and especially the tolerance to a large number of important yet sensitive functional groups, make this method attractive for the streamlined synthesis of functional mols. In the experiment, the researchers used many compounds, for example, 1-Bromo-4-(2-iodoethyl)benzene (cas: 85356-68-9Application In Synthesis of 1-Bromo-4-(2-iodoethyl)benzene).
1-Bromo-4-(2-iodoethyl)benzene (cas: 85356-68-9) belongs to iodide derivatives. In general, organic iodides are light-sensitive and turn yellow during storage, owing to the formation of iodine. The C–I bond is the weakest of the carbon–halogen bonds. These bond strengths correlate with the electronegativity of the halogen, decreasing in the order F > Cl > Br > I. This periodic order also follows the atomic radius of halogens and the length of the carbon-halogen bond.Application In Synthesis of 1-Bromo-4-(2-iodoethyl)benzene
