economical phosphorylation of thiols has been achieved via halogen- and metal-free K2CO3-promoted aerobic oxidative cross-coupling of trialkyl phosphites, dimethyl phenylphosphonite, or methyl diphenylphosphinite with thiophenols using air as the oxidant at room temperature. This transformation provides a straightforward route to the construction of phosphorus–sulfur bonds with wide functional group compatibility

A new and general method for the synthesis of S-, Se-, and Te-aryl phosphorochalcogenoates (chalcogenophosphates) has been developed. S-P, Se-P, and Te-P bonds were formed by the coupling of readily available dialkyl phosphites with diaryl dichalcogenides at 30 ËC in dimethyl sulfoxide in the presence of catalytic amounts of copper iodide and diethylamine. The reaction proceeded smoothly without exclusion of moisture or air.
