摘要：
A complex of ferrous-and hydroxide ions was generated within a core-shell magnetic nanocatalyst of 24 +/- 3 nm. The catalytic activity of material was explored in the synthesis of 3,4-dihydropyrimidine2-(1H)-one/thione (DHPM) derivatives in neat condition. The products are synthesized in high yields (85-98%) in 15-20 min. Neither Fe-nor hydroxide leaching in the reaction medium was detected by AAS and pH analysis, respectively. The catalyst has a convenient reusability after seven consecutive reaction cycles giving a cumulative turnover frequency >5600h(-1). (C) 2017 Elsevier B.V. All rights reserved.
