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.

A novel palladium-catalyzed synthesis of free N-H 2,3-disubstituted indoles from arenediazonium tetrafluoroborates and 2-alkynyltrifluoroacetanilides is presented. The reaction tolerates a variety of useful substituents both in the starting alkyne and the arenediazonium salt, including bromo and chloro substituents, nitro, cyano, keto, ester, and ether groups, as well as ortho substituents such as methoxy and methyl groups.
