“…We studied the PEG-400-mediated synthesis of 3-hydroxy-3-(pyridin-2-ylmethyl)indolin-2-ones (Raghu, Rajasekhar, Reddy, Reddy, & Reddy, 2013), alkyl phosphonates (Mohan Naidu et al, 2011), α-aminophosphonates (Rao, Jayaprakash, Nayak, & Reddy, 2011), α-aminonitriles (Kumar, Babu, Srinivasulu, Kiran, & Reddy, 2007), and its modified catalytic action in the form of PEG-SO 3 H for the synthesis of α-aminophosphonates (Reddy et al, 2012) has driven us to explore its application for the study of some other organic compounds. In this hierarchy, we studied the PEG-400-mediated synthesis of 1,2-disubstituted benzimidazoles and accomplished them with good yields.…”
