A novel palladium-catalyzed synthesis of arylphosphonates from arenediazonium tetrafluoroborates and triethylphosphite or diethylphosphite is presented. The reaction tolerates useful substituents including bromo, chloro, nitro, ether, cyano, keto, and ester groups, can be performed as a one-pot process from anilines omitting the isolation of arenediazonium salts, and can be extended to the preparation of arylphosphine oxides and arylphosphines.

Free NH 3,3-diarylacrylamides are cyclized to substituted 2-quinolones in the presence of CuI, PPh(3), and KO-t-Bu in o-xylene at 100 °C. The reaction proceeds through a C-H functionalization/C-N bond formation process. With unsymmetrical 3,3-diarylacrylamides, high selectivity is observed using substrates where the aromatic ring trans to the amide group bears o-methyl, -chloro, or -bromo substituents.

A palladium‐catalyzed synthesis of aryl—P derivatives from arenediazonium tetrafluoroborates is developed that can be performed as a one‐pot process from anilines.

Starting from unsymmetrical diarylacrylamides regioisomeric mixtures are obtained.
