Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Synlett called Cobalt-Catalyzed Decarboxylative Methylation and Ethylation of Aliphatic N-(Acyloxy)phthalimides with Organoaluminum Reagents, Author is Wang, Ze-Zhong; Wang, Guang-Zu; Zhao, Bin; Shang, Rui; Fu, Yao, which mentions a compound: 693-67-4, SMILESS is CCCCCCCCCCCBr, Molecular C11H23Br, Safety of 1-Bromoundecane.
A cobalt-catalyzed decarboxylative methylation of aliphatic redox-active esters [N-(acyloxy)phthalimides; RAEs] I (R = heptadecyl, 1-[(4-methylphenyl)sulfonyl]piperidin-4-yl, 1-benzoylpyrrolidin-2-yl, 4-(4-chlorophenoxy)butyl, etc.) with trimethylaluminum under mild conditions was developed, providing a method for transforming a carboxylate group into a Me group without redox fluctuation. Primary and secondary RAEs I were both amenable substrates, whereas a tertiary RAE delivered an elimination product. Triethylaluminum was also used to deliver a decarboxylative ethylation product RC2H5.
