(Aminotroponiminato)yttrium Amides as Catalysts in Alkyne Hydroamination
摘要:
The synthesis and characterization of the mono-and bis(N-isopropyl-2-(isopropylamino)troponiminato)yttrium amides [(iPr)(2)ATI]Y[N(SiMe3)(2)](2) and [(iPr)(2)ATI](2)Y[N(SiMe3)(2)], with the corresponding chloro precursors [[(iPr)(2)ATI]YCl2(THF)(2)](2) and [(iPr)(2)ATI](2)YCl as starting materials, is reported together zuith their application as precatalysts for the hydroamination/cyclization of aminoalkynes.
