Levin, Yevgenia; Hamza, Khalil; Abu-Reziq, Raed; Blum, Jochanan published the artcile< Sol-gel entrapped pyridinium hydrobromide perbromide as a recyclable bromination agent: its application to a one-pot bromination and dehydrobromination process>, Electric Literature of 112-63-0, the main research area is bromination solgel entrapped pyridinium hydrobromide perbromide.
Silica sol-gel encaged pyridinium hydrobromide perbromide can be used for clean, odorless bromination of a variety of substrates, including alkenes, ketones, and arenes. The used heterogenized bromination reagent can be recharged with bromine and recycled. In the presence of sol-gel entrapped 1,5,7-triazabicyclo[4.4.0]dec-5-ene, dibromides are dehydrobrominated to give vinyl monobromides and/or alkynes. Encapsulation of the pyridinium derivative and the guanidine base within sep. sol-gel matrixes enables the use of both opposing reagents in one-pot reactions without their mutual destroying each other.
European Journal of Organic Chemistry published new progress about Alkenes Role: RCT (Reactant), SPN (Synthetic Preparation), RACT (Reactant or Reagent), PREP (Preparation). 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Electric Literature of 112-63-0.
