Exempel på hur man kan använda BORYLATION i en mening

• Another application lies in metal-free catalysis: 2-mercaptopyridine can be used as a catalyst for isodesmic C-H borylation of heteroarenes.
• Both verruculogen and its isoprenyl derivative fumitremorgin A belong to the only family of alkaloids with an eight-membered endoperoxide ring, and both have been synthesised involving ligand-controlled C–H borylation.
• Metal-catalyzed C–H borylation reactions are transition metal catalyzed organic reactions that produce an organoboron compound through functionalization of aliphatic and aromatic C–H bonds and are therefore useful reactions for carbon–hydrogen bond activation.
• These include alkylation from alkyl halides, Suzuki-type reaction with boronic esters, borylation with bis(pinacolato)diboron, protonation with i-PrOH, decarboxylative alkynylation with alkynyl carboxylic acids.
• Such compounds, especially those derived from catecholborane and the related pinacolborane, are intermediates in transition metal-catalyzed borylation reactions.
• Complexes of this ligand also catalyze a wide array of reactions, including the arylation of ketones and esters, borylation of aryl chlorides, and the arylation of indoles.
• A heterobimetallic bond-breaking process is also employed in the IPrCuFp-catalyzed C-H borylation system developed by Mankad (Scheme 5).
