Decarboxylative arylation
WebCatalyst-free access to aryldifluoromethyl ketones has been achieved through decarboxylative arylation of α,α-difluoro-β-ketoacid salts using diaryliodonium(iii) salts. The products were successfully transformed into the corresponding esters, amides, and difluoromethyl compounds. This strategy provides acces International Symposium on … WebOct 3, 2024 · Pd-catalyzed or Rh-catalyzed decarboxylative C–H bond arylation of thiophenes, indoles, alkynes and polyfluorobenzene with aryl acids was reported by Su and the co-workers [8c-h]. Recently, decarboxylative acylation reactions of α -oxocarboxylic acids through C–H activation was also developed.
