Ni-Biurea complex anchored onto MCM-41: As an efficient and recyclable nanocatalyst for the synthesis of 2,3-dihydroquinazolin-4(1H)-ones

Novel Ni-Biurea complex supported on functionalized MCM-41 was prepared by introducing nickel salt into mesoporous MCM-41 functionalized with biurea ligand and used as an efficient, recoverable and thermally stable nanocatalyst for the one-pot synthesis of 2,3-dihydroquinazolin-4(1H)-ones.240
