The main products of the reaction of 1,3-dichloro-1,3-dimethyl-1,3-diorganyldisiloxanes with hexamethyldisilazane (molar ratio 1 : 1, 20 °C) are the earlier unknown linear 1-chloro-1,3-dimethyl-1,3-diorganyl-3-(trimethylsilylamino)disiloxanes of the general formula ClMeRSiOSiMeRNHSiMe3 (1) (R = ClCH2 (a), Me (b), Vin (c), Ph (d)) obtained in up to 53—72% yield and 1,3-dimethyl-1,3-diorganyl-1,3-bis(trimethylsilylamino)disiloxanes of the general formula (Me3SiNH)MeRSiOSiMeR(NHSiMe3) (2a—d) (7—12% yield). Thermolysis of compounds 1a—d leads to the formation of cyclic silazaoxanes. A plausible scheme for their formation was suggested.
1,3-dichloro-1,3-dimethyl-1,3-diorganyldisiloxanes 与六甲基二硅氮烷(摩尔比 1 :1 : 1,20 °C)反应得到的通式为 ClMeRSiOSiMeRNHSiMe3 (1) (R = ClCH2 (a),Me (b),Vin (c)、Ph (d)),收率高达 53-72%;以及通式为(Me3SiNH)MeRSiOSiMeR(NHSiMe3)(2a-d)的 1,3-二甲基-1,3-二甘氨酰-1,3-双(三甲基硅烷基氨基)二硅氧烷(收率为 7-12%)。化合物 1a-d 的热分解会导致环状硅氮杂环烷的形成。我们提出了形成这些化合物的合理方案。
