Tritylation of Aromatic Compounds

Synthesis, mesomorphism and electrochemical properties of tetrasubstituted zinc and copper phthalocyanines

“…The initial compounds, 4-triphenylmethylphenol 3 and 4-triphenylmethylaniline 5 were synthesized according to the literature data. 16 A common a Applied Functional Polymers, Department of Macromolecular Chemistry I, University of Bayreuth, 95440 Bayreuth, Germany. E-mail: mukundan.…”

Radical Substitution In Aromatic Nuclei

“…It is doubtful whether similar substitution of phenols, phenolic ethers, amines, and acetylated amines by heating with chlorotriphenylmethane is to be assigned a radical (282) or a carbonium-ion course. Benzene, toluene, chlorobenzene, and methyl benzoate can undergo substitution if they are first converted to aryl radicals.…”

“…Nuclear triphenylmethylation of phenol by the radical (350) surely proceeds by transfer substitution. It is doubtful whether similar substitution of phenols, phenolic ethers, amines, and acetylated amines by heating with chlorotriphenylmethane is to be assigned a radical (282) or a carbonium-ion course.…”

Preparation of TADDOL Derivatives for New Applications

“…While substitutions of chloride with aniline (→ 10 ), a phenol (→ 11 ), and thiophenol (→ 9 ) occurred as expected, we were surprised to isolate trityl derivatives 14 and 15 with N -methylaniline and diphenylamine by simply mixing the components in CH 2 Cl 2 at room temperature; − see the structures of 10 and 14b in Figure .…”
