Abstract
A wide-ranging and practical synthesis of structurally diverse, sterically hindered N-arylpiperazines from 2,2'-(4-nitrophenylsulfonylazanediyl) bis(ethane-2,1-diyl) bis(4-nitrobenzenesulfonate) and substituted anilines has been achieved using microwave irradiation in acetonitrile followed by deprotection with PhSH.
