In 2019,Angewandte Chemie, International Edition included an article by Sun, Haotian; Haque, Farihah M.; Zhang, Yi; Commisso, Alex; Mohamed, Mohamed Alaa; Tsianou, Marina; Cui, Honggang; Grayson, Scott M.; Cheng, Chong. Application In Synthesis of Ethyl 5-bromovalerate. The article was titled 《Linear-Dendritic Alternating Copolymers》. The information in the text is summarized as follows:
Herein, the design, synthesis, and characterization of an unprecedented copolymer consisting of alternating linear and dendritic segments is described. First, a 4th-generation Hawker-type dendron with two azide groups was synthesized, followed by a step-growth azide-alkyne “”click”” reaction between the 4th-generation diazido dendron and poly(ethylene glycol) diacetylene to create the target polymers. Unequal reactivity of the functional groups was observed in the step-growth polymerization The resulting copolymers, with alternating hydrophilic linear and hydrophobic dendritic segments, can spontaneously associate into a unique type of microphase-segregated nanorods in water. After reading the article, we found that the author used Ethyl 5-bromovalerate(cas: 14660-52-7Application In Synthesis of Ethyl 5-bromovalerate)
Ethyl 5-bromovalerate(cas: 14660-52-7) belongs to bromides. Most organobromine compounds, like most organohalide compounds, are relatively nonpolar. Bromine is more electronegative than carbon (2.9 vs 2.5). Consequently, the carbon in a carbon–bromine bond is electrophilic, i.e. alkyl bromides are alkylating agents.Application In Synthesis of Ethyl 5-bromovalerate
