Abstract Aminobisphenol supported germylenes (1a–3a), stannylenes (1b–3b) and plumbylenes (1c–3c) were synthesized by reaction of Lappert’s tetrylenes, [(Me3Si)2N]2M (M = Ge, Sn, Pb), with corresponding aminobisphenols R1N(CH2C6H2(OH)(t-Bu)R2)2, 1–3 (1: R1 = Et, R2 = Me; 2: R1 = Et, R2 = t-Bu; 3: R1 = CH2(Py-2), R2 = t-Bu). X-ray diffraction analysis revealed different coordination mode for germylene
摘要通过拉珀特的四甲苯[(Me3Si)2N] 2M(M = Ge,Sn,Pb)与相应的对苯二酚反应,合成了氨基双酚负载的亚二甲基亚砜(1a-3a),亚苯乙烯基(1b-3b)和亚铅基(1c-3c)。氨基双酚R1N(CH2C6H2(OH)(t-Bu)R2)2,1-3(1:R1 = Et,R2 = Me; 2:R1 = Et,R2 = t-Bu; 3:R1 = CH2(Py- 2),R2 = t-Bu)。X射线衍射分析表明,亚甲基3a和亚锡3b的配位方式不同,在配体的结构中还带有氮供体。通过与Re(CO)5Br的反应,将二甲基亚甲基1a转化为the络合物1aa。
