The activity of a simple, commercially available copper salt, [Cu(NCMe)4](BF4) in intramolecular hydroamination reactions of alkynes and allenes is presented. Reactions were successfully carried out in technical acetonitrile in the presence of air. While attempts of alkene hydroamination failed, this catalyst was also found active in intermolecular aza-Michael reactions.

(Chemical Equation Presented) Intramolecular hydroamination of several aminoalkynes catalyzed by silver-phenanthroline complexes is reported. This catalyst system complements previous protocols by employing air- and moisture-stable complexes without compromising activity or reaction control. Some of the hydroamination products are subject to a useful aerobic oxidation. Silver-phenanthroline complexes have successfully demonstrated efficacy in the desymmetrization of a prochiral diyne.

A series of yttrium and lanthanide amido complexes [Ln{N-(SiHMe 2)2}2{CH(PPh2NSiMe3) 2}] (Ln = Y, La, Sm, Ho, Lu) were synthesized by three different pathways. The title compounds can be obtained either from [Ln{N(SiHMe 2)2}3(thf)2] and [CH 2(PPh2NSiMe3)2] or from KN-(SiHMe2)2 and [Ln(CH(PPh2NSiMe 3)2}-Cl2]2, while in a third approach the lanthanum compound was synthesized in a one-pot reaction starting from K{CH(PPh2NSiMe3)2}, LaCl3, and KN-(SiHMe2)2. All the complexes have been characterized by single-crystal X-ray diffraction. The new complexes, [Ln{N(SiHMe 2)2}2{CH(PPh2NSiMe3) 2}], were used as catalysts for hydroamination/cyclization and hydrosilylation reactions. A clear dependence of the reaction rate on the ionic radius of the center metal was observed, showing the lanthanum compound to be the most active one in both reactions. Furthermore, a combination of both reactions - a sequential hydroamination/hydrosilylation reaction - was also investigated.
