Abstract
Whereas biphenyl-4,4′-dicarbonyl dichloride reacts with methylenetriphenylphosphorane to give the expected bis(acylylide) 1, the same reaction of biphenyl-2,2′-dicarbonyl dichloride results in a multistep rearrangement leading to the zwitterionic 2-[1,3-bis(triphenylphosphonio)prop-1-en-3-id-2-yl]biphenyl-2′-carboxylate 2. X-ray crystal structures of both 1 and 2 are reported.
