Raje, Vivek P.,Bhat, Ramakrishna P.,Samant, Shriniwas D.
, p. 2676 - 2678 (2006)
Polyvinyl pyridine (PVP) is prepared by radical polymerization of 4-vinyl pyridine. PVP was used as a heterogeneous basic catalyst for the aza-Michael reaction of secondary amines and carbamates with α,β-unsaturated esters, cyanides and ketones to obtain the corresponding adducts in excellent yields (70-90%).

Iranian dolomite (CaMg(CO3)2) which consists of double-layered carbonates with Ca2+ and Mg2+ ions was utilized as a heterogeneous base catalyst in the CC, CN, and CS bond forming reactions via the Henry, Knoevenagel, aza-Michael, and thia-Michael transformations under mild conditions in water. Iranian dolomite has been characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), Brunauer Emmett Teller (BET) and XRF chemical analysis, while its basic strength was evaluated by following the Hammett indicators procedure. This water-insoluble natural catalyst demonstrated high activity and was reusable.
