Several methylesters of 3-dialkylamino-substituted n- and isobutyric acids have been subjected to electrochemical fluorination to give the corresponding perfluoroacid fluorides. Dimethyl, diethyl, pyrrolidino, morpholino, piperidino and N-methylpiperazino groups were investigated as dialkylamino substituents. The structure/yield relationship was evaluated both in terms of the structure of the acid and
very simple conjugate addition of aromatic and aliphatic amines to α,β-unsaturated carbonyl compounds under solvent-free conditions in the presence of catalytic amount of silicontetrachloride is reported. The reaction of aryl and alkyl amines with different Michael acceptors gave the corresponding Michael adducts with simple catalyst and good to excellent yields.

and quantitative procedure for Michael additionreactions between various amines and α,β-unsaturated carbonyl compounds and nitriles in the presence of an easily accessible basicionicliquid – 3-butyl-1-methylimidazolium hydroxide, [bmIm]OH – as both catalyst and reactionmedium has been developed. For large-scale reactions the products could be directly distilled from the ionicliquid, allowing the

A series of cationic (diphosphine)palladium(II) complexes have been prepared and fully characterized, including two crystal structures. These complexes were evaluated as catalysts for the hydroamination of acyclic alkenes. The reactivity of the catalysts is dependent on the nature of the diphosphine ligand and the substituents on the amine and alkene substrates. (C) 2002 Elsevier Science B.V. All rights reserved.
