solid equimolar adducts of ammonia and SiH3Y formulated from their i.r. spectra as NH4+(YSiH3)–; N-methyldisilylamine and N-dimethylsilylamine react similarly but more rapidly. Reactions of the ammonium salts with Mel, with Me3SiCl, with GeH3Br, and with PF2Br are described. With acetyl chloride, the esters MeC(O,Y)·SiH3 are formed; n.m.r. spectra indicate that in these compounds there is intramolecular
三甲
硅烷基胺在室温下与H 2 Y(Y = S或Se)反应,生成(SiH 3)2 Y以及由
氨和SiH 3 Y的红外光谱确定为NH 4 +(YSiH 3)–的固体等摩尔加合物。N-甲基二甲
硅烷基胺和N-二甲基甲
硅烷基胺反应相似,但反应更快。描述了
铵盐与Mel,Me 3 SiCl,GeH 3 Br和PF 2 Br的反应。与
乙酰氯,酯MeC(O,Y)·SiH 3形成; 核磁共振谱表明,在这些化合物中,O和Y之间存在SiH 3分子内交换,在室温下快速,但在低于–50°的温度下慢。当Y = S时,主要的异构体是MeC(:S)·O·SiH 3;当Y = Se时,异构体CH 3 ·C(∶O)·Se·SiH 3 ∶MeC(∶Se)·O·SiH 3的比例为约3。2·5。
