Polyethylene Gylcol (PEG-400) as an efficient and Recyclable ReactionMedium for the one pot synthesis of 3, 3’-Di (indolyl) oxindoles undercatalyst-Free conditions

[摘要] Polyethylene glycol (PEG) was found to be an inexpensive nontoxic and effective medium for the one-pot synthesis of 3, 3’-Di (indolyl) oxindoles under catalyst-free conditions in excellent yields. Environmental acceptability, low cost, high yields, and recyclability of the PEG are the important features of this protocol.
