HPLC of Formula: 1129-28-8In 2022 ,《BF3 Mediated [1,5]-Hydride Shift Triggered Cyclization: Thioethers Join the Game》 was published in European Journal of Organic Chemistry. The article was written by Zaitseva, Elvira R.; Smirnov, Alexander Yu.; Timashev, Vladimir I.; Malyshev, Vadim I.; Zhigileva, Ekaterina A.; Mikhaylov, Andrey A.; Medvedev, Michael G.; Baleeva, Nadezhda S.; Baranov, Mikhail S.. The article contains the following contents:
2-(2-(Benzylthio)benzylidene)malonates can underwent the 1,5-hydride shift triggered cyclization resulting in thiachromanes in 45-84% yield. Boron trifluoride as a reaction promotor is the key to success. DFT calculations revealed that the reaction proceeds via a chelate BF2 complex, which was confirmed by NMR-anal. Exptl. and theor. comparison of nitrogen, sulfur and carbon analogs revealed that sulfur derivatives have the highest activation barrier for the hydride transfer due to the unfavorable transition state geometry, which explains the lack of previous reports on 1,5-hydride shifts in (alkylthio)styrenes. In the experimental materials used by the author, we found Methyl 3-(bromomethyl)benzoate(cas: 1129-28-8HPLC of Formula: 1129-28-8)
Methyl 3-(bromomethyl)benzoate(cas: 1129-28-8) belongs to organobromine compounds.Organobromine chemicals are produced naturally by an array of biological and other chemical processes in our environment. Organobromine compounds are produced naturally by marine creatures (sponges, corals, sea slugs, tunicates, sea fans) and seaweed, plants, fungi, lichen, algae, bacteria, microbes, and some mammals.
