Triple Hydrogen Bonding for Stereospecific Radical Polymerization of a DAD Monomer and Simultaneous Control of Tacticity and Molecular Weight was written by Wan, Decheng;Satoh, Kotaro;Kamigaito, Masami. And the article was included in Macromolecules in 2006.Synthetic Route of C7H9N3O This article mentions the following:
A triple hydrogen bonding interaction effectively controlled the stereochem. during radical polymerization of acrylamide derivatives An acrylamide monomer, in which amide (proton donor site, D) and pyridine (proton acceptor site, A) moieties were arrayed in the DAD sequence, was polymerized in the presence of a cyclic imide as the ADA-type receptor in CHCl3 to give syndiotactic polymers (r = 72%) even at 60 °C while atactic polymers (r = 43%) were obtained without the mediator. Furthermore, the simultaneous control of the tacticity and the mol. weights of the polymers were attained by RAFT polymerization in the presence of the mediator. In the experiment, the researchers used many compounds, for example, N-(6-Aminopyridin-2-yl)acetamide (cas: 1075-62-3Synthetic Route of C7H9N3O).
N-(6-Aminopyridin-2-yl)acetamide (cas: 1075-62-3) belongs to pyridine derivatives. In contrast to benzene, Pyridine’s electron density is not evenly distributed over the ring, reflecting the negative inductive effect of the nitrogen atom. One of the examples of pyridines is the well-known alkaloid lithoprimidine, which is an A3 adenosine receptor antagonist and N,N-dimethylaminopyridine (DMAP) analog, commonly used in organic synthesis.Synthetic Route of C7H9N3O
