B(OMe)3 as a nonacidic iminium ion generator in Mannich- and Ugi-type reactions
Tanaka, Yusuke,Hidaka, Kousuke,Hasui, Tomoaki,Suginome, Michinori

Mannich-type reactions of aldehydes with secondary amines and a ketene silyl acetal were promoted by trimethoxyborane in DMSO to afford the corresponding β-amino esters in good yields. B(OMe)3 also promoted Ugi-type reactions of aldehydes with
Cu(acac)2 immobilized in ionic liquids: A recoverable and reusable catalytic system for aza-Michael reactions

Copper(II) acetylacetonate immobilized in ionic liquids efficiently catalyzes the aza-Michael reaction of amines with α,β-unsaturated carbonyl compounds to produce the corresponding β-amino carbonyl compounds with great alacrity in excellent yields. The reactions are far more facile than those reported earlier. The recovered ionic liquid phase containing the copper catalyst can be reused for several cycles with consistent activity.
Air- and moisture-stable cationic (diphosphine)palladium(II) complexes as hydroamination catalysts X-ray crystal structures of two complexes
Li, Kelin,Horton, Peter N.,Hursthouse, Michael B.,Hii, King Kuok Mimi
, p. 250 - 257 (2007/10/03)
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.
