摘要：

A novel approach to poly-functionalized furan synthesis is disclosed via oxidative decarboxylative [3+2] cycloaddition using co-operative catalysis by visible light and CoFe2O4 nanoparticles under ambient reaction conditions with water as a solvent. Although the reported method is efficient without catalyst in the presence of visible light (70% yield in 4 h at rt), the use of catalyst not only increases the yield (91%) but also accelerates the conversion rate (2 h at rt).
