preparation of functionalized 4,4′-bisquinolones using a microwave-assisted Ullmann-type homocoupling reaction is described. The method is catalytic in nickel(0) which is generated in situ by reduction from an inexpensive nickel(II) source and utilizes readily available 4-chloroquinolin-2(1H)-ones as starting materials. In contrast to the alternative palladium(0)-catalyzed one-pot borylation/Suzuki cross-coupling

Functionalized 4,4‘-bisquinolones can be efficiently synthesized by microwave-assisted palladium(0)-catalyzed one-pot borylation/Suzukicross-coupling reactions or via nickel(0)-mediated homocouplings of 4-chloroquinolin-2(1H)-one precursors. Both methods are also applicable to other types of symmetrical biaryls.
