In 2022,Yu, Lefei; Zhou, Qi; Gao, Yunpeng; Fu, Zihao; Xiao, Yiyang; Li, Zi-Chen; Wang, Jianbo published an article in Chemical Communications (Cambridge, United Kingdom). The title of the article was 《Synthesis of polyallenoates through copper-mediated cross-coupling of dialkynes and bis-α-diazoesters》.HPLC of Formula: 609-14-3 The author mentioned the following in the article:
The copper-catalyzed cross-coupling of alkynes and α-diazoesters has been applied in the synthesis of polyallenoates for the first time. The polymerization tolerated various functional groups and afforded the polyallenoates with high mol. weight With chiral guanidinium bromide as a ligand, the axial chirality of the allene moiety could be generated with high enantioselectivity during the polymerization process. In the part of experimental materials, we found many familiar compounds, such as Ethyl 2-methyl-3-oxobutanoate(cas: 609-14-3HPLC of Formula: 609-14-3)
Ethyl 2-methyl-3-oxobutanoate(cas: 609-14-3) belongs to ketone compounds. They are most widely used as solvents, especially in industries manufacturing explosives, lacquers, paints, and textiles. Ketones are also used in tanning, as preservatives, and in hydraulic fluids.HPLC of Formula: 609-14-3
