Reaction of haloarenetricarbonylchromium with trimethylphosphite: palladium-catalyzed Arbuzov reaction versus arene displacement by trimethylphosphite

The Arbuzov reaction of trimethylphosphite with p-bromo-, and also with p-chloro-toluenetricarbonylchromium is achieved at 80-120 deg C, in the presence of a Pd0 or PdII complex, which acts as a catalyst.A competitive displacement of

Photoinduced Transition-Metal-Free Cross-Coupling of Aryl Halides with H-Phosphonates

Photoinduced transition-metal- and photosensitizer-free cross-coupling of aryl halides (including Ar-Cl, Ar-Br, and Ar-I) with H-phosphonates (including dialkyl phosphonates and diarylphosphine oxides) is reported. Various functional groups were tolerated, including ester, methoxy, dimethoxy, alkyl, phenyl, trifluoromethyl, and heterocyclic compounds. This simple and green strategy provides a practical pathway to synthesize arylphosphine oxides.

Copper-catalyzed coupling reaction of arylhydrazines and trialkylphosphites

A novel CuO-catalyzed coupling reaction of arylhydrazines with trialkyl phosphites to afford arylphosphonates is described. The reaction proceeded at 80 C in air without external reductants, oxidants, and ligands.
