[(kappa(3)-(tBu)CN(H)C(tBu))PdCl][Cl] (14) coordination of NHC moieties and amine nitrogen atom is observed between -40 and 25 degrees C. Reaction between 12-14 and two equivalents of AgBF(4) in acetonitrile gives the analogous complexes [trans-(kappa(2)-(tBu)CN(Bn)C(tBu))Pd(MeCN)(2)][BF(4)](2) (15), [trans-(kappa(2)-(Mes)CN(H)C(Mes))Pd(MeCN)(2)][BF(4)](2) (16) and [(kappa(3)-(tBu)CN(H)C(tBu))Pd(MeCN)][BF(4)](2)

Electron-deficient olefins undergo smoothly aza-Michael reactions with a wide range of amines in ionic liquids in the absence of any acid catalyst to produce the corresponding β-amino compounds in excellent yields with high 1,4-selectivity. The recovered ionic liquids can be reused in subsequent reactions without loss of activity. Owing to the high polarity of ionic liquids, the enones show enhanced reactivity thereby reducing reaction times and improving the yields significantly.

Chiral ferrocenyl tridentate phosphine ligands were synthesized and used in asymmetric hydroamination reactionscatalyzed by Ni(II)-complexes. Compounds of the type [Ni(PPP)L]2+, where L is a chloride, solvent molecule or a coordinated substrate, were isolated. The efficiency of these complexes in asymmetric catalysis was high when aliphatic or aromatic amines were reacted with electron-poor olefins
