Chemistry can be defined as the study of matter and the changes it undergoes. 70918-54-6. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.70918-54-6, Name is (S)-1,4-Benzodioxane-2-carboxylic acid, molecular formula is C9H8O4, introducing its new discovery.
Silver-catalyzed decarboxylative alkynylation of aliphatic carboxylic acids in aqueous solution
C(sp3)-C(sp) bond formations are of immense interest in chemistry and material sciences. We report herein a convenient, radical-mediated and catalytic method for C(sp3)-C(sp) cross-coupling. Thus, with AgNO3 as the catalyst and K2S2O8 as the oxidant, various aliphatic carboxylic acids underwent decarboxylative alkynylation with commercially available ethynylbenziodoxolones in aqueous solution under mild conditions. This site-specific alkynylation is not only general and efficient but also functional group compatible. In addition, it exhibits remarkable chemo- and stereoselectivity.
