complex (3) showed a modulated behavior: at room temperature, (3) still slowly eliminates mainly chlorotrimethylsilane with the formation of [(i-PrO)2P(NSiMe3)2]GeCl (6). Structure of this chlorinated germanium(II) compound which can also be seen as a germyl anion has been evidenced by an X-ray analysis. But at higher temperature (40–50 °C) (3) mainly decomposes with elimination of isopropylchloride leading
摘要P-双(三甲基甲硅烷基)氨基-N-(三甲基甲硅烷基)亚氨基膦在0°C下与各种二烷氧基二氯锗烷(烷氧基:OR = OMe,OEt和Oi-Pr)的反应产生稳定的二氯锗烯络合物[(RO) 2P(NSiMe3)(N(SiMe3)2)] GeCl2 [R = Me(1),Et(2)和R = i-Pr(3)]。(2)的固态结构已经通过X射线晶体学确定。基于在异丙氧基衍生物的情况下观察到的瞬时物种,提出了形成这些化合物的机理。在室温下在苯溶液中,化合物(1)和(2)消除三甲基氯硅烷而无副反应,从而导致相应的2,4-二氮杂-3-磷酸三mat [[RO] 2P(NSiMe3)2] GeCl(4)和(5 ), 分别。相反,复合物(3)表现出调制行为:在室温下,(3)仍然缓慢地主要消除三甲基氯硅烷,并形成[(i-PrO)2P(NSiMe3)2] GeCl(6)。通过X射线分析已经证明了该氯化锗(II)化合物
