The carbonylative coupling of aryl halides with unactivated alkenes remains a challenge, because of the low reactivity of acyl-palladium intermediate to the olefins. A palladium-catalyzed carbonylative coupling/amination of aryl iodides with unactivated alkenes for the synthesis of β-aminoketone derivatives was developed. With the assistance of a directing group (8-aminoquinoline, AQ), the coordination of the olefin to acyl-palladium complex can be enhanced, thereby promoting the acylpalladation across the C:C double bonds. A broad range of β-aminoketone derivatives were prepared in moderate to excellent yields with complete regioselectivity by using 4-pentenoic and 2-vinylbenzoic amide derivatives as the starting materials. This methodol. involves the formation of two C-C bonds as well as one C-N bond, and provided a method for the carbonylative difunctionalization of unactivated alkenes. In the experiment, the researchers used many compounds, for example, 4-Iodo-1,2-dimethoxybenzene (cas: 5460-32-2Recommanded Product: 5460-32-2).
4-Iodo-1,2-dimethoxybenzene (cas: 5460-32-2) belongs to iodide derivatives. Typical reactions of alkyl iodides include nucleophilic substitution, elimination, reduction, and the formation of organometallics. A typical method for synthesis of aromatic iodides is diazotization of primary aromatic amines followed by treatment of potassium iodide. Aliphatic alcohols are converted to alkyl iodides by treating with hydrogen iodide.Recommanded Product: 5460-32-2
