An efficient synthesis of 5-phosphorylated uracil derivatives has been carried out via an oxidative cross-coupling reaction between uracil derivatives and dialkyl phosphites in the presence of Mn(OAc)(3) in AcOH. (c) 2013 Elsevier Ltd. All rights reserved.

yields. Csp2-phosphorous bond can also be easily created in a photochemical version of the Arbuzov reaction. With UVA and a stoichiometric amount of trimethyl phosphite, the corresponding phosphonates were isolated in good to high yields. Very interesting selectivities were observed under these mild irradiation conditions. Functionalized substrates can be engaged and the resulting products could be
