Hou, Jun-Tao,Gao, Jian-Wu,Zhang, Zhan-Hui
experimental part, p. 495 - 499 (2011/12/16)
A novel and efficient procedure was developed for the preparation of diaminotriarylmethanes through the Baeyer condensation of aromatic aldehydes and N,N-dimethylaniline or N,N-diethylaniline in the presence of niobium chloride under solvent-free conditio
SbCl3-catalyzed one-pot synthesis of 4,4′-diamino- triarylmethanes under solvent-free conditions: Synthesis, characterization, and DFT studies
Bardajee, Ghasem Rezanejade
experimental part, p. 135 - 144 (2011/05/16)
A simple, efficient, and mild procedure for a solvent-free one-step synthesis of various 4,4′-diaminotriarylmethane derivatives in the presence of antimony trichloride as catalyst is described. Triarylmethane derivatives were prepared in good to excellent yields and characterized by elemental analysis, FTIR, 1H and 13C NMR spectroscopic techniques. The structural and vibrational analysis were investigated by performing theoretical calculations at the HF and DFT levels of theory by standard 6-31Gs *, 6-31G*/B3LYP, and B3LYP/cc-pVDZ methods and good agreement was obtained between experimental and theoretical results.
ZrOCl2 catalyzed Baeyer condensation: A facile and efficient synthesis of triarylmethanes under solvent-free conditions
Reddy, Ch Sanjeeva,Nagaraj,Srinivas,Reddy
experimental part, p. 248 - 254 (2009/12/03)
A facile and efficient synthesis of an array of triarylmethanes by the Baeyer condensation of different arylaldehydes carrying activated and deactivated groups and N,N-dimethyIaniline using a catalytic amount of ZrOCI2 under solvent-free microwave irradiation conditions is described. Further, the catalytic activity of ZrOCI2 is compared with traditional Lewis acid catalysts and found that this synthetic method has the advantages of excellent yields (70-96%), shorter reaction time (few minutes) and solvent-free conditions.
Fluorinated analogs of malachite green: Synthesis and toxicity
Kraus, George A.,Jeon, Insik,Nilsen-Hamilton, Marit,Awad, Ahmed M.,Banerjee, Jayeeta,Parvin, Bahram
, p. 986 - 994 (2008/09/20)
A series of fluorinated analogs of malachite green (MG) have been synthesized and their toxicity to Saccharomyces cerevisiae and a human ovarian epithelial cell line examined. The toxicity profiles were found to be different for these two species. Two ana
Color intensity control in polymers using triarylmethane leuconitriles as color formers
Malpert, John H,Grinevich, Oleg,Strehmel, Bernd,Jarikov, Viktor,Mejiritski, Alexander,Neckers, Douglas C
, p. 967 - 974 (2007/10/03)
Several triarylmethane leuconitriles have been synthesized. Color formation rates of triarylmethane dyes from corresponding leuconitriles have been compared in various media. Routes to color-on-demand processes are discussed.
