(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)2S and (Et3Si)2E (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 1H NMR spectroscopy. The solid‐state structures of the homoleptic complex 1 and the
M(OCH 2 CH 2 N R 2)2型的分子内稳定的锗,锡和铅的醇盐[ R = Et,M = Ge(1); R = Me,M = Sn(2);R = Me,M = Pb(3)]是与(Me 3 Si)2 S加扰反应中合成第14组硫族化物ME(M = Ge,Sn,Pb; E = S,Se,Te)的合适前体。和(Et 3 Si)2 E(E = Se,Te)在中等温度下通过热注射方法。反应通过消除相应的甲硅烷基醚来进行,如通过原位1 H NMR光谱法证实的。通过单晶X射线衍射确定了均配物1和杂配物ClGe(OC 2 H 4 NEt 2)(4)的固态结构,而第14族硫属化物的特征在于XRD,SEM和EDX。
