The first insertion of a silylene into a MN bond was observed in the presented transformations of the thermally stable silylene 1 , Np = neopentyl, with metal( II ) bis(silyl)amides. Bis(silyl)metal( II ) compounds 2 and 3 were obtained for M = Sn and Pb, respectively, whereas a colorless azadisilager‐mole was formed for M Ge. Noteworthy is the very long SnSi bond of 2.712(2) Å in 2 .
