HPLC of Formula: 3395-91-3In 2020 ,《Byproducts formed During Thiol-Acrylate Reactions Promoted by Nucleophilic Aprotic Amines: Persistent or Reactive?》 was published in ChemPlusChem. The article was written by Drogkaris, Vasileios; Northrop, Brian H.. The article contains the following contents:
The nucleophile-initiated mechanism of thiol-Michael reactions naturally leads to the formation of undesired nucleophile byproducts. Three aza-Michael compounds representing nucleophile byproducts of thiol-acrylate reactions initiated by 4-dimethylaminopyridine (DMAP), 1-methylimidazole (MIM), and 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) have been synthesized and their reactivity in the presence of thiolate has been investigated. Spectroscopic anal. shows that each nucleophile byproduct reacts with thiolate to produce a desired thiol-acrylate product along with liberated aprotic amines DMAP, MIM, or DBU, thus demonstrating that these byproducts are reactive rather than persistent. D. functional theor. computations support exptl. observations and predict that a β-elimination mechanism is favored for converting each nucleophile byproduct into a desired thiol-acrylate product, though an SN2 process can be competitive (i. e. within <2.5 kcal/mol) in less polar solvents. The results came from multiple reactions, including the reaction of Methyl 3-bromopropanoate(cas: 3395-91-3HPLC of Formula: 3395-91-3)
Methyl 3-bromopropanoate(cas: 3395-91-3) belongs to bromides. One prominent application of synthetic organobromine compounds is the use of polybrominated diphenyl ethers as fire-retardants, and in fact fire-retardant manufacture is currently the major industrial use of the element bromine.HPLC of Formula: 3395-91-3
