Oligomeric Benzylsulfonium Salts: Facile Benzylation via High-Load ROMP Reagents was written by Zhang, Mianji;Flynn, Daniel L.;Hanson, Paul R.. And the article was included in Journal of Organic Chemistry in 2007.Recommanded Product: 58759-63-0 This article mentions the following:
The development of high-load, oligomeric benzylsulfonium salts, generated via ring-opening metathesis polymerization, and their utility in facile benzylations of various nucleophiles is reported. These oligomeric sulfonium salts exist as free-flowing powders and are stable at room temperature After the benzylation event, purification is attained via simple dry load/filtration, followed by solvent removal to deliver products in excellent yield and purity. In the experiment, the researchers used many compounds, for example, 5-Nitrobenzothiazole-2-thiol (cas: 58759-63-0Recommanded Product: 58759-63-0).
5-Nitrobenzothiazole-2-thiol (cas: 58759-63-0) belongs to thiazole derivatives. The thiazole ring is notable as a component of the vitamin thiamine (B1). The nitrogen in thiazole is sp2 hybridized and the lone pair of electrons localized on the nitrogen is less reactive due to increased aromatic character and decreased basicity. It is protonated and alkylated/acylated at nitrogen forming hydrochloride and quaternary thiazolium salt.Recommanded Product: 58759-63-0
