Bose, Ajay K.,Pednekar, Suhas,Ganguly, Subhendu N.,Chakraborty, Goutam,Manhas, Maghar S.
, p. 8351 - 8353 (2004)
Solvent-free reactions that are complete in a few minutes. Grindstone Chemistry - a greatly evolved version of Toda's method of grinding solids together for solvent-free chemical reactions - has been described and its usefulness illustrated by the success
Immobilized Cu(I) on organic-inorganic hybrid material: An effective and reusable catalyst for Biginelli reaction
Zhang, Xiao L.,Wang, Min,Wang, Lei
, p. 577 - 581 (2011)
The immobilized Cu(I) on organic-inorganic hybrid material was prepared and used as effective catalyst for the Biginelli reaction. In the presence of immobilized copper catalyst, aromatic aldehydes reacted with β-keto ester and urea (or thiourea) smoothly
