Cobalt coupling systems

WebThe first cobalt-catalyzed cross-coupling of aryl tosylates with alkyl and aryl Grignard reagents is reported. The catalytic system uses CoF 3 and NHCs (NHC=N-heterocyclic carbene) as ancillary ligands. The reaction proceeds via highly selective C−O bond functionalization, leading to the corresponding products in up to 98 % yield. WebCobalt Coupling Centralizers operate successfully at temperatures up to 350 F (175 C), proven performance, reduced coupling "wobble" to prevent Hole-In-Tubing failures. Cobalt® Patented Technology More USA patents for Cobalt that showcase our innovative developments in artificial lift, corrosion control and additive manufacturing.
