A new Pd/MgLa mixed oxide and the known Pd/MgAl hydrotalcite catalysts were applied and recycled successfully in catalytic transfer hydrogenation reactions in ionic liquidsSome α,β-unsaturated carboxylic acid derivatives were hydrogenated in excellent yields.The catalysts were recycled without significant loss of activity.Besides that, a number of halogenated aromatic compounds were dehalogenated under similar catalytic transfer conditions.

A review on the preparation and reactions of pyrido[2,1-b][1,3]oxazines, pyrido[2,1-b][1,3]thiazines and pyrido[1,2-a]pyrimidines.

A review on structure, reactivity, and synthesis of pyrido-oxazines, pyrido-thiazines, pyrido-diazines and their benzologs is presented.
