Silica (NPs) supported Fe (III) as a reusable heterogeneous catalyst for the one-pot synthesis of 1, 4-dihydropyridines under mild conditions
Javad Safaei-Ghomi Abolfazl Ziarati Safura Zahedi
A cheap and recyclable silica (NPs) supported Fe (III) was prepared as heterogeneous catalyst for the synthesis of various substituted 1,4-dihydropyridines via condensation of aldehydes with ethyl acetoacetate and ammonium acetate in ethanol. The products were separated from the catalyst simply by filtration and the catalyst could be recycled and reused for several times without noticeable decrease in the catalytic activity.

Silver iodide nanoparticle as an efficient and reusable catalyst for the one-pot synthesis of benzofurans under aqueous conditions
Javad Safaei-Ghomi Mohammad Ali Ghasemzadeh
Recyclable heterogeneous AgI nanoparticles were efficiently catalysed one-pot three-component reaction of aldehydes, secondary amines and alkyne in aqueous media. This method provides a novel and improved approach for the synthesis of 2,3-disubstituted benzo[b]furan derivatives to obtain excellent yields, short reaction times and low catalyst loading.

The reaction of carbon disulphide with 𝛼-haloketones and primary amines in the presence of potassium iodide as catalyst
Javad Safaei-Ghomi Fariba Salimi Ali Ramazani
A simple, mild and convenient method has been developed for the synthesis of 3,4,5-trialkyl-1,3-thiazole-2(3𝐻)-thione derivatives through one pot three-component reaction between a primary amine, carbon disulphide, and 𝛼-haloketone in the presence of potassium iodide at room temperature conditions. The products were obtained with excellent yield and appropriate reaction times. This reaction represents a rapid and unprecedented route to the described molecules that have biological specifications.
