The conjugate addition of anilines onto unsaturated ketones, esters and N-acylpyrroles was investigated. Based on a recently proposed explanation for the phenomenon of on-water catalysis, operationally simple and mild reaction conditions for effecting these addition reactions have been developed. The success of these additions provides further support for the acid-catalysed nature of on-water chemistry.
Zirconium Tetrakis(dodecylsulfate) as an Efficient and Recyclable Lewis Acid-Surfactant-Combined Catalyzed C-C and C-N Bond Forming Under Mild and Environmentally Benign Conditions
A green catalytic method for C-C and C-N bond forming via Michaeladdition of aromatic amines and indoles to electron-deficientolefins using Zirconium tetrakis(dodecylsulfate) in water under mild conditions with high yields and selectivity has been developed. The reusability of the catalyst has been successfully examined without any noticeable loss of its catalytic activity.
