A novel displacement of certain activated aromatic nitro-groups by tervalent organophosphorus reagents is described. Thus trimethyl, triethyl, and tri-isopropyl phosphites, diethyl methylphosphonite, and ethyl diphenyl-phosphinite react with increasing ease [(RO)3P < (EtO)2PMe < EtOPPh2] with o-dinitrobenzene to give high yields of the corresponding dialkyl o-nitrophenylphosphonates, ethyl P-methy
