چکیده
|
In this study, 5-benzoyl-6-phenyl-4- (4- (trifluoromethoxy) phenyl) - 1,2,3,4-tetrahydroxypyrimidine (1); 5-benzoyl-6-phenyl-4- (4- (trifluoromethoxy) phenyl) -1,2,3,4-tetrahydrothioxypyrimidine (2) and 5-benzoyl-6-phenyl-4- (3,5-dimethoxy) phenyl) -1,2,3,4-tetrahydrothioxypyrimidine (3) compounds were prepared via biginelli condensation reaction usingmetal-organic framework (mil-101) as an active catalyst. it was established to be an active heterogeneous catalyst for a three-component biginelli condensation reaction with good yields (75-80 %).moreover, the catalyst could easily be recovered and recycled without any significant loss of its catalytic activity. also the compounds 5-benzoyl-6-phenyl-3-acetyl-4-(4-hydroxyphenyl)-1,2,3,4-tetrahydrothioxypyrimidine (4) and 5-benzoyl-6-phenyl-3-acetyl-4-(4-trifluoromethoxy)phenyl)-1,2,3,4-tetrahydrothioxypyrimidine (5) were obtained acetylation reaction. the structures were characterized on the basis of 1 h-nmr, 13 c-nmr, ft-ir, and elemental analysis. and also molecular characterizations of compound 4 were analyzed by x-ray crystal analysis. in addition,the corrosion inhibition activity of synthesized compounds was examined with theoretical calculation using dft method at the level of b3lyp / 6-31g (d, p).
