solubility, meltingpoint and mixed meltingpoint) as resulted by oxidation of the product obtained via p-toluenesulfenyl chloride and l-chloro-l-nitroethane. The low yield of sulfone is associated with the presence of considerable p-tolyl disulfide in the oily product subjected to oxidation. The disulfide was separated and its identity confirmed by meltingpoint and mixed meltingpoint with authentic

Aminescontaining the trimethylsilylmethyl (Me3SiCH2−) group have been used in the preparation of a range of transition metalcomplexes. With one exception the amines underwent reaction by simple co-ordination, but [Ru3H(CO)10(CNMe2)] was formed by the fragmentation of the amine Me3SiCH2NMe2 (and also from Me3SnCH2NMe2). Where the free amines possessed either a chiral or prochiral centre that was rendered
含有三甲基甲硅烷基甲基(Me 3 SiCH 2-)基团的胺已用于制备一系列过渡金属配合物。除了一个例外,胺通过简单的配位进行反应,但是[Ru 3 H(CO)10(CNMe 2)]是通过胺Me 3 SiCH 2 NMe 2(也由Me 3 SnCH 2 NMe )的断裂而形成的2个)。在游离胺具有手性或手性中心的情况下,通过在氮原子上快速金字塔式转化,在NMR时间尺度上无法观察到,而在“转化-冻结”的金属络合物中,相关的等时质子是可辨别的。

, said reaction comprising the following steps: a) reacting the (haloorganyl)silane of the general formula (3) and the (aminoorganyl)silane of the general formula (2) at a temperature of 0 to 250° C. to form, as well as the silylorganoamine of the general formula (1), the ammonium halide of the (aminoorganyl)silane of the general formula (2) as a by-product, b) adding a base (B), which results in complete or partial ester interchange, in which the (aminoorganyl)silane of the general formula (2) is released again and forms the halide of the base (B), the halide of the base (B) being liquid at temperatures of at most 200° C., and c) removing the liquid halide formed from the base (B).
