Abstract:	The N,N-diethylpropylamine supported on amorphous silica (KG-60-NEt₂) catalyses the formation of carboncarbon bonds by nitroalkanes through both the nitroaldol (Henry) and Michael reactions. The catalyst shows general utility with a variety of electrophilic acceptors. Moreover, the catalyst can be reused for two further cycles without loss of the activity.

Keywords:	nitroaldol (Henry) reaction Michael reaction nitroalkanes heterogeneous catalysis
