Abstract
Potassium phosphate and silica sulfuric acid have been found to be useful, highly efficient catalysts for conjugate addition of thiols to α,β-unsaturated ketones under solvent-free conditions, at room temperature. Silica sulfuric acid (SSA) was found to be suitable for electron-deficient enones while potassium phosphate was found to effect thia-Michael addition with both electron-deficient and electron-rich conjugated ketones.
