“…Thus, the nitration of 2,2‐bis(4‐hydroxyphenyl)propane was the first step of the monomer synthesis. The facility of phenol nitration resulted in the problem of multisubstitution of the aromatic ring by the nitro group 23, 24. Therefore, new methods and conditions of carrying out this reaction were sought 25.…”

A number of NLO polymers were obtained, in which aromatic polyester is a matrix and the chromophores are incorporated into the form of a side chain. Special monomers are based on 2,2-bis(3-amino-4-hydroxyphenyl)propane; they contain an azomethine bond and various electron-acceptor groups (nitro, cyanide, and fluoride) as substituents in the side-chain aromatic ring. The effect of the type of the electronacceptor substituent, its substitution position in the aromatic ring with respect to the azomethine bond, and special monomer concentration on the optical, mechanical, and thermal properties of the whole system was studied.

“…The nitration of aromatic compounds may be achieved with many nitrating reagents and is a very useful reaction in organic synthesis. Nitration of the phenol as a special case has been studied using various nitrating agents under different conditions [ 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 ]. Recently, in this connection we have reported the applications and mechanism of reaction of some hydrated metal nitrates and their dinitrogen tetroxide complex analogues for the nitration of phenols under various conditions [ 21 ].…”

“…Also, nitro compounds find use in many industrial applications [ 2 , 3 , 4 ]. Nitration of phenol as a special case has been studied using various nitrating agents under different conditions [ 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 ]. Recently, in this connection we have reported the use and reaction mechanisms of some hydrated metal nitrates (containing covalent nitrato groups) and their dinitrogen tetroxide complex analogues for the nitration of phenols under various conditions [ 23 ].…”
