چکیده

The tin pyrophosphate (SnP۲O۷) was synthesized from the modification of mono-ammonium phosphate (MAP) by tin chloride (SnCl۲). This solid was used as a heterogeneous catalyst for the one-pot multicomponent synthesis of tetrahydrobenzo[b]pyran and dihydropyrano[۳,۲-c]chromenes derivatives under green reaction conditions. This synthetic protocol offers several advantages such as short reaction times (۸-۱۵ min), high product yields (۸۵-۹۷%), easy work‐up procedure, and easy catalyst separation from the reaction mixture. In addition, SnP۲O۷ can be recycled for up to five cycles without a significant loss of catalytic reactivity. The XRD and IR spectra confirm the stability and heterogeneity of SnP۲O۷ in the reaction medium even after its reuse.
