A new hybrid material of NaY zeolite supported 1-sulfonic acid-3-methyl imidazolium ferric chloride [Msim][FeCl4] has been developed by modifying the zeolite surface with six different w/w ratios through wet impregnation method. These composite

A series of 4-aryl-2-cyanoimino-3,4-dihydro-1H-pyrimidines was obtained as a result of a multicomponent Biginelli reaction using 1,3-dicarbonyl compounds, aromatic aldehydes, and cyanamide. Alkylation of the obtained compounds with benzyl chloride takes place at the two nitrogen atoms of the tetrahydropyrimidine ring, while oxidation with manganese dioxide leads to the corresponding 1-(pyrimidin-2-yl)carbamides or pyrimidine-2-amines, depending on the conditions.
