The aim of this work is
to prove the efficiency of the Phosphate fertilizers mono-ammonium phosphate
(MAP), di-ammonium phosphate (DAP) and triple-super phosphate (TSP) as a
“green” heterogeneous catalysts for the synthesis of 2-aryl-2H-benzo[b][1,4]thiazin-3(4H)-ones
via the C-S and C-N coupling process of gem-dicyano epoxide with
α-aminothiophenol. To optimize the reaction conditions, the synthesis was
conducted with a range of solvents, catalyst amounts and catalyst particle
sizes. Also, the potential recyclability of the catalysts was confirmed by
running the reaction using the recycled catalyst.
