iodide-accelerated, palladium-catalyzed C–P bond-forming reaction of aryl nonaflates is described. The protocol was optimized for the synthesis of aryl phosphine oxides and was found to be tolerant of a wide range of aryl nonaflates. The general nature of this transformation was established with coupling to other P(O)H compounds for the synthesis of aryl phosphonates and an aryl phosphinate. The straightforward
Herein, NiCl2 was employed as a cheap precatalyst in the formation of C(sp2)-P bond via cross coupling reaction of phenol derivates and phosphine oxides/phosphites. This method allows a variety of phenols with diverse functional groups to transform to phosphates with good yields. No additional additive was used in this reaction.

(major) and the corresponding 2-halogenophenyldiphenylphosphine oxide. No trace of furan–dehydrobenzene adduct was observed in these reactions; however, 1- and 2-naphthyldiphenylphosphine oxides (9:4) were detected. These compounds were the major products from the reaction of the furan–dehydrobenzene adduct with diphenylphosphide, although the ratio of 1- to 2-isomers was quite different (1:9) in this

We herein reported the synthesis of organophosphorus(V) compounds through the coupling of readily available starting materials in the presence of recyclable g-CN as photocatalyst. These reactions showed wide functional group tolerance and were performed at rt under visible-light irradiation. The catalyst could be easily separated and reused, thus implying the great potential of use in industry for
