Abstract

Abstract A new high??yielding, operationally simple, solvent??free, and mild method for preparation of pyrazolines, tetrahydrocarbazoles, and indoles has been developed using KHSO4· H2O impregnated on SiO2. The reactions have been probed under microwave irradiation (MWI), and ultrasonic and thermal conditions, employing different solid supports. The data revealed that KHSO4· H2O impregnated on SiO2 under MWI provides the best ...
