    Abstract: Method for preparing bibenzyl systems with nitro groups as substituents. Toluene derivates with nitro groups are coupled oxidatively in methanolic alkali solution under influence of metal catalysts. The oxidation is preferably done with air. As catalysts metal acetonylacetonates are used. The metal can be Ni, Cu, Co, Mn, Cr or Ti. This catalyst can be used together with a crown ether. Another suitable catalyst is a metal tetraphenylporphin of porfyrin type where the metal can be Ni, vanadium (V=O) or Fe(FeIII).

    Abstract: Nitro-isopropenyldiphenyl ethers are provided which can serve as a useful source of known monomer intermediates or as intermediates for the preparation of nitro-haloisopropyl substituted diphenyl ethers. The latter have been discovered to act as facile alkylating agents with phenols providing nitro-p-hydroxyphenylisopropyl substituted diphenyl ethers. When the latter compounds are reduced there are obtained the corresponding amino-p-hydroxyphenylisopropyl substituted diphenyl ethers.The polymerization of this last class of compounds with acid halides provides polyamide-esters. The polymers can be used in the manufacture of such articles as tubing, hose, bellows hose, and the like.
