Synthesis of tetrahydrobenzo[b]pyran under catalysis of NH4Al(SO4)2·12H2O (Alum)
Arabian Journal of Chemistry, 2017 AbstractA simple and efficient one-pot synthesis of tetrahydrobenzo[b]pyrans from the three-component reaction between dimedone, aldehydes, and active methylene compounds using NH4Al(SO4)2·12H2O (Alum) as a catalyst at 80°C is described. The catalyst exhibits remarkable reactivity and is reusable.

Abstract This study explores the development and use of a novel 2D MOF as a heterogeneous catalyst in organic synthesis. The phosphonocarboxylic acid m-PO3CH2C6H4CO2H (L) has been employed in the synthesis of a metal carboxyarylphosphonate. The 2D MOF [Cu(H2O)(m-PO3CH2C6H4CO2H)]n (1) was synthesized in both crystal (1) and nanostructure (1 ...
