The significant differences in catalytic performance when compared …
WebPd is most commonly used precious metal for hydrogenation and this is rated at high risk of depletion. No concern for abundant base metals like Ni, Cu etc. If aryl iodides are used, incineration of waste streams could be problematic (iodine content). Limited utility for waste by-products. Iodine is an element at medium to high risk of depletion. WebApr 7, 2024 · The above are all Pd‐NHCs catalyzed Suzuki‐Miyaura and Buchwald‐Hartwig cross‐coupling of amides by selective C−N(O) cleavage with η 3 ‐allyl‐Pd coordination mode. These catalysts were used to catalyze amide C−N bonds cleavage for the first time, opening a new chapter in amide activation.
