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

Transformation of H 2 PtCl 6 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 H 2 PtCl 6 ⋅ 6H 2 O–2-octanol solution is hydrochlorinated to give 2-chlorooctane. Dehydrated platinum chlorides c...

Description
Summary:Transformation of H 2 PtCl 6 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 H 2 PtCl 6 ⋅ 6H 2 O–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 H 2 PtCl 4 with octene-1 is not stable in a hydrochloric medium and rapidly decomposes to release chloroalkyl.
