cross-coupling of azoles [C(sp2)–H] with dialkylphosphites [P(O)–H] to access 2-phosphonated azoles using Cu(I)/Cu(II) as catalyst and K2S2O8/di-tert-butylperoxide as oxidant has been achieved. A remarkable advantage over reported procedures includes that oxazoles, imidazoles, benz(ox/othi/imid)azoles, and indole are found to react under optimized reactionconditions to provide corresponding adducts in
