General description
1,2-Dibromobenzene, also known as o-Dibromobenzene, is an aromatic halogenated hydrocarbon commonly used as a precursor in various organic synthesis reactions based on the intermediate formation of benzynes.
Application
- Selective Covalent Capture of Collagen Triple Helices with Minimal Protecting Group Strategy: This study details the use of Rink Amide MBHA resin for capturing collagen triple helices, highlighting its efficiency in solid-phase synthesis (JDH Le Tracy Yu, 2020).
- Solid phase peptide synthesis: new resin and new protecting group: Introduction of a novel resin, Fmoc-Rink-Amide PEG Octagel, showcasing its application in peptide synthesis (S Ramkisson, 2018).
- Development of a novel, automated, robotic system for rapid, high-throughput, parallel, solid-phase peptide synthesis: This paper discusses the utilization of Rink Amide MBHA resin in developing an automated system for peptide synthesis (K Kiss et al., 2023).
- Synthesis of Peptoids Containing Multiple Nhtrp and Ntrp Residues: A Comparative Study of Resin, Cleavage Conditions and Submonomer Protection: The study compares different resins including Rink Amide MBHA, analyzing their efficacy in peptoid synthesis (A Lone et al., 2020).
It is also used as a key reactant in the synthesis of:
- diborylbenzenes via palladium-catalyzed borylation of bromobenzenes
- o,o′-tri- and -tetrasubstituted biphenyls via aryne cross-coupling reaction
