Novel silica-supported molybdic acid (SSMA): an efficient catalyst for the synthesis of new azo dyes
- 99 Downloads
Silica-supported molybdic acid (SSMA) as a novel and highly efficient catalyst was prepared and characterized by X-ray fluorescence, X-ray diffraction, and Fourier transform infrared spectroscopy. Catalytic activity of as-prepared SSMA was then investigated for synthesis of novel azo coumarin dyes. This convenient and efficient protocol provides better alternatives to existing methods because the reactions proceeded quickly under clean conditions with high yields.
