Description
Summary:This work demonstrates the effectiveness of vigorously stirred lanthanum oxide (La 2 O 3 ) suspensions in catalyzing Michael additions in water. These surfactant-free suspensions offer a counterintuitive yet highly efficient approach compared to traditional methods. Notably, the reactions are ineffective in the absence of water, suggesting a crucial role for the aqueous environment. Vigorously stirred La 2 O 3 suspensions in water demonstrated exceptional efficiency ( e.g. high yields, short reaction times) for carbon-carbon bond formation. Water proved irreplaceable by organic solvents despite the reactant(s) being immiscible.
