Präparative Darstellung von Disilanyl- und Trisilanyljodiden

摘要

The preparation of Si2H5J as well as Si2H4J2(SiH3−SiHJ2+SiH2J−SiH2J), Si3H7J (SiH3−SiH2−SiH2J+SiH3−SiHJ−SiH3) and Si3H6J2(isomeric mixture) by reaction of the corresponding silanes with elementary iodine without using a solvent is communicated. The reaction of iodine with silanes is accelerated by catalysings amounts of alcohol. At the same time, however, the cleavage of the Si−Si-bond
