The methyl methacrylate (MMA; Alfa Aesar, Warsaw, Poland) was dried using molecular sieves (type 4Å, Chempur, Piekary Śląskie, Poland). The [2-(methacryloyloxy)ethyl]-trimethylammonium chloride (TMAMA/Cl; 80% aq. solution, Sigma-Aldrich, Poznań, Poland) was dried to a constant weight under reduced pressure. Methanol and tetrahydrofuran (THF) were purchased from Chempur (Piekary Śląskie, Poland) and dried over the same molecular sieves as MMA. Copper(I) bromide (CuBr; Fluka, 98%, Steinheim, Germany) was purified using a procedure described previously in the literature [42 (link)]. N,N,N′,N″,N″-pentamethyldiethylenetriamine (PMDETA, 98%), ethyl 2-bromoisobutyrate (EBiB, 98%), potassium clavulanate (KCLV), and bis(trifluoromethane)sulfonimide lithium salt (LiTf2N) were obtained from Sigma Aldrich (Poznań, Polska). Sodium p-aminosalicylate (NaPAS, 98%), sodium piperacillin (NaPIP, 99%), and sodium fusidate (NaFUS, 98.8%) were purchased from Alfa Aesar (Warsaw, Poland) and used without further purification.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
