چکیده انگلیسی
The catalytic efficiency of various metallophthalocyanines was investigated for three-component condensation reaction of aldehyde, β-dicarbonyl compound and urea to afford corresponding 3,4-dihydropyrimidinones. These phthalocyanine complexes were found to be efficient, recyclable heterogeneous catalyst and showed rate enhancements, high yields and short reaction times in this transformation. Among the various metallophthalocyanines studied, cobalt(II)- phthalocyanine was found to be most active for this transformation.
