Abstract: A simple,economic and efficient one pot synthesis of some sub s tituted 2-o xo-1,2,3,4-t etrahydropyr imid ines [3, 4- dihydropyrimidin-2(1<i>H</i> )-ones) and 2-thioxo-1,2,3,4-tetrahydropyrimidines under solvent free condition and microwave irradiation catalyzed by tin(II) chloride dihydrate and tin (II) i ide is described. Aromatic aldehydes, possessing either electron donating or electron withdrawing substituents, react efficiently with urea (or thiourea) and <img src='/image/spc_char/beta.gif' border=0>-dicarbonyl compounds to give excellent yield of sub s tituted 3,4-dihydro pyrimidin-2 (1<i>H</i> )-ones (o r 3, 4-dihydropyrimidin-2(1<i>H</i> )-thiones].
