The reaction of triarylantimony diacetates [Ar3Sb(OAc)(2)] with dialkyl H-phosphites [H-PO(OR)(2)] in the presence of a Pd(PPh3)(4) (5 mol%) catalyst led to the formation of arylphosphonates in moderate to excellent yield under base-free conditions. This reaction is the first example of carbon-phosphorus bond formation by using an organoantimony compound as a pseudo-halide.
