Metallated ynamines 5a-f and ynehydrazines 5g,h were prepared in a very short reaction sequence by consecutive treatment of trichloroethylene (1) with the lithium salt of secondary amines or of trimethylhydrazine, 2 equivalents of butyllithium and chlorotriorganosilanes or -stannanes.

trichloroethylene - lithium amides - lithium trimethylhydrazide - N-(1,2-dichlorovinyl) derivatives - N-(silylethynyl-, stannylethynyl)amines and -trimethylhydrazines
