The development of a highly efficient, polystyrene-supported NHC–Ag(I) catalyst for the three-component coupling reactions of aldehydes, alkynes, and amines (A 3 -coupling) was described. In the presence of PS–NHC–Ag(I) (2mol%), the A 3 -reactions were carried out at room temperature under solvent-free reaction conditions and the corresponding propargylamines were generated in good...
An efficient and convenient method for the direct hydroalkylation of styrene and norborene with 1,3-diketones has been developed by using 12-phosphotungstic acid as an eco-friendly, and air- and moisture-tolerable catalyst. Reactions proceeded without any solvent, providing a clean access to alkylated 1,3-diketones.
