Intramolecularly‐stabilized germanium, tin, and lead alkoxides of the type M (OCH 2 CH 2 N R 2 ) 2 [ R = Et, M = Ge ( 1 ); R = Me, M = Sn ( 2 ); R = Me, M = Pb ( 3 )] are suitable precursors for the synthesis of group 14 chalcogenides ME ( M = Ge, Sn, Pb; E = S, Se, Te) in scrambling reactions with (Me 3 Si) 2 S and (Et 3 Si) 2 E ( E = Se, Te) at moderate temperatures via hot injection method. The reactions proceed with elimination of the corresponding silylether as was proven by in situ 1 H NMR spectroscopy. The solid‐state structures of the homoleptic complex 1 and the heteroleptic complex ClGe(OC 2 H 4 NEt 2 ) ( 4 ) were determined by single‐crystal X‐ray diffraction, whereas the group 14 chalcogenides were characterized by XRD, SEM, and EDX.
