Solvent-Free Henry and Michael Reactions with Nitroalkanes Promoted by Potassium Carbonate as a Versatile Heterogeneous Catalyst

The use of a simple weak inorganic base such as potassium carbonate facilitated the formation of carbon-carbon bonds through both the henry and the michael reactions with nitrocompounds. the application of this catalyst under environmentally friendly solventless heterogeneous conditions gave satisfactory to good yields of β-nitroalcohols,involving aliphatic and aromatic starting materials,as well as high to excellent yields in the formation of michael adducts using several different michael acceptors and nitroalkanes. © 2017 giovanna bosica and kurt polidano.
