Preparation of di and tri(bis(indolyl) methanes) from di and trialdehydes and indoles in the presence of silica sulfuric acid was described. Reactions proceeded in good to excellent yields in acetonitrile as solvent at room temperature.
Some new metal dodecyl sulfates were prepared by the reaction of sodium dodecyl sulfate and the corresponding metal nitrates. All of the prepared salts catalyzed the condensation of indoles with aldehydes and ketones. Among of them, zirconium tetrakis(dodecyl sulfate), Zr(DS) 4 , was superior to others. Bis- and tris-indolyl methanes were synthesized at room temperature in high yields by using...
