p-Nitrobenzyl phosphonate anion with p-nitrocumyl halides gives a good yield of the coupling product dialkyl[(1,1-dimethyl-1,2-di-(p- nitrobenzyl)ethyl] phosphonates through the S(RN)1 mechanism. The reaction was greatly accelerated by sunlamp irradiation but inhibited by the radical scavenger (t-Bu)₂NO^..
