Buchwald-hartwig cross coupling reaction
WebMar 13, 2024 · Cross-coupling reactions with [B12H11I]2− as one partner have been used successfully for Kumada and Buchwald Hartwig couplings with Pd catalysis. Here, we found that the iodide could be substituted easily, and unexpectedly, with other halides … WebA popular method is the Buchwald–Hartwig reaction : (Eq.1) Miscellaneous reactions [ edit] Palladium-catalyzes the cross-coupling of aryl halides with fluorinated arene. The process is unusual in that it involves C–H functionalisation at an electron deficient arene. [17] …
