synthesized with high diversity in three steps from arylhalides, terminal alkynes, and primary amines. The reaction sequence starts with a palladium-catalyzed coupling of an arylhalide and a terminal alkyne (Sonogashira coupling). A subsequent Cp2TiMe2-catalyzed hydroamination of the obtained alkyl(aryl)alkyne, which takes place regioselectively in the 2-position, gives access to an α-arylketimine
