N,N-Bis(2-hydroxyethyl) alkylamide or fatty acid diethanolamides (FADs) were prepared from a variety of triglycerides using diethanolamine in the presence of different transition metal-doped CaO nanocrystalline heterogeneous catalysts. The Zn-doped Cao nanospheroids were found to be the most efficient heterogeneous catalyst, with complete conversion of natural triglycerides to fatty acid diethanolamide in 30 min at 90 °C. The Zn/CaO nanoparticles were recyclable for up to six reaction cycles and showed complete conversion even at room temperature. The amidation reaction of natural triglycerides was found to follow the pseudo-first-order kinetic model, and the first-order rate constant was calculated as 0.171 min–1 for jatropha oil aminolysis. The activation energy (Ea) and pre-exponential factor (A) for the same reaction were found to be 47.8 kJ mol–1 and 4.75 X 108 min-1, respectively.

A series of 2,4,6-triarylpyridines have been prepared using a variety of aromatic and heteroaromatic aldehydes in the presence of aluminum phosphate (AlPO4) as a heterogeneous catalyst at 120 oC under solvent-free conditions. The present methodology offers several advantages such as excellent yields, simple procedure, shorter reaction times, milder conditions and the catalyst exhibited remarkable reusable activity. Keywords: Aluminum phosphate; 2,4,6-triarylpyridines; One-pot synthesis; Shorter reaction times;  Reusable activity.  © 2010 JSR Publications.

: An efficient four-component reaction to synthesize pyrrolo[2,1-a]isoquinolines from malononitrile, aromatic aldehydes, isoquinoline, and cyclohexyl isocyanide under solvent-free conditions is described. In a convenient, simple, and efficient one-pot procedure, the domino Knoevenagel-nucleophilic cycloaddition reaction affords excellent yields of products in less than 1 h.
