reacts with Y(SiH3)2(Y = O, S, or Se) or Z(SiH3)3(Z = P or As) in diethyl ether to give Li(YSiH3) or Li[Z(SiH3)2]; these compounds have been characterised by i.r., Raman, and n.m.r. spectroscopy, and some of their reactionswith halides have been studied. Trisilylamine does not react cleanly with LiMe to form an analogous compound. The n.m.r. spectra of solutions containing both Li(YSiH3) and Y(SiH3)2
甲基锂与Y(SiH 3)2(Y = O,S或Se)或Z(SiH 3)3(Z = P或As)在乙醚中反应生成Li(YSiH 3)或Li [Z( SiH 3)2 ]; 这些化合物已通过红外光谱,拉曼光谱和核磁共振光谱进行了表征,并研究了它们与卤化物的某些反应。三甲硅烷基胺不能与LiMe干净地反应形成类似的化合物。包含Li(YSiH 3)和Y(SiH 3)2的溶液的nmr光谱表明,除非Y = O,否则交换会在nmr时间尺度上快速发生。可以从Li(SeSiH 3)制备硒代乙酸硅酯)和MeCOCl,并确定了该物种中分子内交换的动力学参数。
