Provided herein are fluoropicolinoyl fluorides and processes for their preparation. In some embodiments, provided herein is a process for the preparation of 5-fluoro-6-aryl- picolinoyl fluorides from chloropicolinoyl chlorides.
The example of palladium-catalyzed intermolecular cyclization for the synthesis of various diarylfurans in which one of the aromatic rings originates from the phenolic part of the starting ester and the other one from PhI(OAc)2 has been reported. The reaction is carried out through two steps: the rearrangement of palladium-associated iodonium ylides to form o-iodo diaryl ether and then palladium catalyzed
