A new, facile, efficient, “green” and chemoselective procedure for the synthesis of indole derivatives has been developed with pulverization-activation method catalyzed by Bi(NO3)3·5H2O (PAMC- Bi(NO3)3·5H2O) through grinding of indoles with aldehydes or Michael acceptors in the presence of catalytic amounts of Bi(NO3)3·5H2O undersolvent-freeconditions.

Abstract An operationally simple and green method for the synthesis of a wide range of bis(indolyl)methanes, and N,N′ -alkylidene bisamides under mild conditions, with excellent yields using Silzic, has been developed. This improved method furnishes in good yields bis(indolyl)methanes derivatives starting from indole and aldehydes, or ketones, and N,N′ -alkylidene bisamides derivatives starting from
A fast, solvent-free solid acid mediated synthetic strategy for the synthesis of bisindolylmethanes has been developed. The process is applicable to a wide range of substrates with different protecting group survival properties. Reusability of Fe/Al pillared clay for more than 5 cycles without significant loss of catalytic activity adds to the features of the reaction.

improved protocol for the synthesis of bis(indolyl)methanes using 6 mol% [BCMIM][Cl] ionicliquid via facile, one-pot, metal-free synthesis in aqueous ethanol at ambient temperature. In 15–55 min, a series of 48 derivatives were obtained in up to 94 % yields and were characterized using several spectroscopic techniques. UV–visible and fluorescence spectroscopies were used to investigate the photophysical behaviour
