An efficient heterogeneous iron oxide nanoparticle catalyst for the synthesis of 9-substituted xanthene-1,8-dione

Abstract: An efficient and simple method for the synthesis of xanthene derivatives by using iron oxide nanoparticles (NPs) as a catalyst has been investigated. Synthesis of 9-substituted xanthene-1,8-dione derivatives involves one-pot reaction of dimedone

Tungstophosphoric acid nanoparticles supported on polyamic acid: A mild and recoverable heterogeneous catalyst for the selective synthesis of mono and bulky bis(1,8-dioxooctahydroxanthene)s under solvent-free conditions

A series of 1,8-dioxooctahydroxanthene derivatives and some crowded bis(1,8-dioxooctahdroxanthene) were selectively synthesized using tungstophosphoric acid nanoparticles supported on polyamic acid (TPA/PAA) as a new catalyst in solvent-free conditions. T

A green and efficient procedure for one-pot synthesis of xanthenes and acridines using silica boron-sulfuric acid nanoparticles (SBSANs) as a solid Lewis-protic acid

Silica boron-sulfuric acid nanoparticles (SBSANs) as a solid Lewis-protic acid have been found to be an efficient heterogeneous catalyst in the synthesis of xanthene and acridine derivatives. The SBSAN-catalyzed reaction between carbonyl compound (aldehyd
