Abstract
Ni‐PEG (polyethylene glycol) complex supported on magnetic nanoparticle was created by grafting. The catalytic activity of Fe 3 O 4 @PEG–Ni was explored through one‐pot green synthesis of 2,3‐dihydroquinazolin‐4(1 H )‐ones and used as an efficient and recoverable nanocatalyst. FT‐IR, XRD, EDS, BET, TGA, VSM and SEM techniques were employed to specify the nanocatalyst. This heterogeneous nanocatalyst demonstrated acceptable recyclability and could be reused several times with no considerable loss of its catalytic activity.
