Abstract: Abstract We have reported NiFe2O4@SiO2@Melamine for the first time to catalyzed one-pot three components synthesis of spiropyrans and spiroacenaphthylenes via the reaction of ninhydrin/acenaphthoquinone, malononitrile/ethyl cyanoacetate and various 1,3-dicarbonyl compounds. Nickel ferrite nanoparticles were modified… read more here.
