nano-sbcl5/sio2 as an efficient catalyst for one-pot synthesis of 2, 4, 5-trisubstituted imidazoles under solvent- free condition

Nano-SbCl5/SiO2 as an Efficient Catalyst for One-Pot Synthesis of 2, 4, 5-Trisubstituted Imidazoles Under Solvent- Free Condition

A general synthetic route to the synthesis of imidazoles has been developed using nano SbCl5/SiO2 under solvent-free conditions. The multi-component reactions of aldehydes, benzil and ammonium acetate were carried out to afford some trisubstituted imidazole derivatives. This method provides several advantages like simple work-up, environmentally benign, and shorter reaction times along wi...

Caro’sacid-silicagel: An Efficient and Reusable Catalyst for the Synthesis of 2, 4, 5- Trisubstituted Imidazoles under Solvent-free Conditions

Caro’s acid-silicagel was found to be a mild and effective catalyst for the one –pot multicomponent condensation of benzyl, aldehydes and ammonium acetate used for synthesis of 2, 4, 5-trisubstituted imidazole derivatives under solvent–free conditions. This catalyst has several advantages such as simple work-up, low cost and reusability.

Nano Silica Phosphoric Acid: An Efficient Catalyst for the One- Pot Synthesis of 1, 2, 4, 5-Tetrasubstituted Imidazoles

Two  simple  protocols  for  the  synthesis  of  1,  2,  4,  5-   tetrasubstitutedimidazoles  using  nano-SPA  as  a  reusable,  eco-   friendly,  inexpensive,  and  efficient  catalyst  are  reported.  Short   reaction  times,  high  yields,  scale-up  and  easy  workup  are  the   advantages of these protocols.
