Pd(0)-Catalyzed CO Gas-Free Carbonylation of 2-Bromobiphenyls with Formaldehyde as a Carbonyl Surrogate through the Cleavage of a C-H Bond

Paraformaldehyde serves as a carbonyl source in the Pd-catalyzed cyclocarbonylation of 2-bromobiphenyls through the cleavage of a C–H bond to afford good yields of fluoren-9-one derivatives. This p...
