Aryl triflates, carbamates, and sulfonamides are also viable substrates for the amidations, which proceed at 45−110 °C with 1−4 mol % of Pd catalyst in 66−99% yields and exhibit …
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 such as Br and Cl, and with pseudohalides such as cyanide, azide, and isocyanate. We found that … WebIn organic chemistry, the Buchwald–Hartwig amination is a chemical reaction for the synthesis of carbon–nitrogen bonds via the palladium-catalyzed coupling reactions of …
