P-Nitrodiphenyl ethers

Aromatic and aliphatic amino ethers have been synthesized by this method. An example of the formation of a cyano ether is the preparation of p-cyano benzyl methyl ether from the substituted benzyl bromide and sodium methoxide (84%). Also, certain aryloxyacetonitriles, AtOCHjCN, are made by the condensation of chloroacetonitrile with sodium phenoxides in a solution of methyl ethyl ketone containing a small amount of sodium iodide (70-80%). Aromatic nitro ethers, like o- and p-nitrodiphenyl ether, have been prepared by the Ullmann procedure (84%). The synthesis of alkyl p-nitrophenyl ethers has also been accomplished with good yields (55-92%). ...

Copper powder is used as catalyst in the reaction of sodium with aniline to form the sodium derivative, CgHiNKNa. An active copper powder is preferred as catalyst for the synthesis of p-nitrodiphenyl ether" and o-methoxydiphenyl ether. The active catalyst is prepared by reducing copper siilfale in aqueous solution with zinc dust and leaching the precipitate with S% hydrochloric acid to remove excess... 

Diphenylethers. Different agents can induce peroxidations in photosynthetic membranes. The strongest peroxidative herbicides known are the p-nitrodiphenyl ethers. Although compounds from this group of herbicides can act multifunctionally as electron-transport inhibitors U, 2 ) and energy-transfer inhibitors (1 0), some of them, like oxyfluorfen, exert their dominant phytotoxic action by damaging membrane components. 

As this group contains also several acids, phenols and esters, it is to be expected that AMR is not a good descriptor of the compounds lipophilicity and/or steric bulk of the real functional groups, which may be different from groups Z . For example, the diphenylphosphate (Z = OPO(OH)-OCgH5) has the highest AMR (39.73) within the subset, but a much lower log P (1.3) than the p-nitrodiphenyl ether (Z = O-CgH -NOj) with a log P of 3.97.
