Intramolecularly-stabilized Group 14 Alkoxides - Promising Precursors for the Synthesis of Group 14-Chalcogenides by Hot-Injection Method: Intramolecularly-stabilized Group 14 Alkoxides - Promising Precursors for the Synthesis of Group 14-Chalcogenides by Hot-Injection Method

Intramolecularly-stabilized germanium, tin, and lead alkoxides of the type M(OCH2CH2NR2)(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 (Me3Si)(2)S and (Et3Si)(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 H-1 NMR spectroscopy. The solid-state structures of the homoleptic complex 1 and the heteroleptic complex ClGe(OC2H4NEt2) (4) were determined by single-crystal X-ray diffraction, whereas the group 14 chalcogenides were characterized by XRD, SEM, and EDX.
