Abstract
Boron Nitride (BN) efficiently catalyzes the conjugate addition of sulfur and nitrogen nucleophiles to α,β- unsaturated ketones, sulfone, phosphonate, amides, nitriles and esters under solvent-free condition in good yields at room temperature. The attributes of this protocol are operational simplicity, recyclability, high yields of products, innocuous catalyst and solvent-free condition.
Keywords: Hetero-Michael reaction, Boron Nitride, Solvent-free condition, Thiols, Amines, α, β-unsaturated compounds.
