چکیده
The heteroleptic calcium amides [{ArNC(Me)CHC(Me)NAr}Ca(NR(2))(THF)] (Ar=2,6-di-iso-propylphenyl, R=SiMe(3), Ph) and the homoleptic heavier alkaline earth amides, [M{N(SiMe(3))(2)}(2)] (M=Ca, Sr and Ba) are reported as pre-catalysts for the hydroamination of isocyanates.

Mixed-metal reagents [NaMg(CH2SiMe3)3] (1) and [(THF)NaMg(NPh2)3(THF)] [3-(THF)(2)] can act as precatalysts to selectively promote the hydroamination/trimerization of isocyanates (RNCO) depending on the steric bulk of the R substituent.

متن کاملMerging rhodium-catalysed C–H activation and hydroamination in a highly selective [4+2] imine/alkyne annulation
Catalytic C-H activation and hydroamination represent two important strategies for eco-friendly chemical synthesis with high atom efficiency and reduced waste production. Combining both C-H activation and hydroamination in a cascade process, preferably with a single catalyst, would allow rapid access to valuable nitrogen-containing molecules from readily available building blocks. Here we repor...
