Synthesis of fluoren-9-ones by a Rh-catalyzed intramolecular C?H/C?I carbonylative coupling of 2-iodobiphenyls using furfural as a carbonyl source is presented. The findings indicate that the rate-determining step is not a C?H bond cleavage but, rather, the oxidative addition of the C?I bond to a RhI center.

Despite its synthetic potential, intramolecular acylation by the Minisci reaction remains unexplored. The development of a new intramolecular Minisci acylation under silver-free neutral conditions providing access to azafluorenones and fluorenones is described. Distinct from the current literature known approaches for Minisci acylation, the report described herein features a method that: (a) avoids the use of silver that is invariably used in Minisci acylation, (b) does not require any acidic conditions for the activation of pyridines, and (c) shows tolerance to functional groups under neutral conditions.
