摘要

利用NMR、IR、GLC和GC/MS研究了H2PtCl6在2-辛醇作用下随时间的转化。首次发现H2PtCl6·6h2o - 2-辛醇溶液中的醇发生氢氯化反应生成2-氯辛烷。脱水氯化铂催化消除三甲基氯硅烷和六甲基二硅氧烷中的甲基，从而形成聚二甲基硅氧烷。假设H2PtCl4与辛烯-1的π配合物在盐酸介质中不稳定，并迅速分解释放氯烷基。

Processes in H2PtCl6 ⋅ 6H2O–Solvent Systems. Part I: Alcohol Solutions

Transformation of H₂PtCl₆ over time under the action of 2-octanol has been studied by NMR, IR spectroscopy, GLC, and GC/MS. It has been found for the first time that the alcohol in a H₂PtCl₆ ⋅ 6H₂O–2-octanol solution is hydrochlorinated to give 2-chlorooctane. Dehydrated platinum chlorides catalyze the elimination of methyl groups in trimethylchlorosilane and hexamethyldisiloxane, which leads to the formation of polydimethylsiloxanes. It has been assumed that the resulting π-complex of H₂PtCl₄ with octene-1 is not stable in a hydrochloric medium and rapidly decomposes to release chloroalkyl.

期刊介绍： Doklady Chemistry is a journal that publishes new research in chemistry and chemical engineering of great significance. Initially the journal was a forum of the Russian Academy of Science and published only best contributions from Russia in the form of short articles. Now the journal welcomes submissions from any country in the English or Russian language. Every manuscript must be recommended by Russian or foreign members of the Russian Academy of Sciences.
