文摘

[Chol][Pro] was supported on different porous carbon materials. Subsequently, the catalytic activity of the heterogeneous systems in the Michael reaction between cyclohexanone and β-nitrostyrene was studied. Excellent conversions and high diasteroselectivities were attained by supporting [Chol][Pro] on the heat treated mesoporous carbons. The stability of the [Chol][Pro] and consequently, its catalytic activity were strongly influenced by the textural and surface chemical properties of the carbon supports.
