Abstract : It was found that gas phase thermolysis of mu-(CH3)3SiB5H8 at about 80C results in irreversible formation of 2-(CH3)3SiB5H8 at a reasonable rate. At higher temperatures further isomerization occurs to produce 1-(CH3)3SiB5H8. This isomerization, however, is reversible and 1-(CH3)3SiB5H8 predominates by a factor of about 3.3 at 120C. Gas phase thermolysis of 2-H3SiB5H8 at 150C results in a similar conversion to 1-H3SiB5H8. This isomerization also appears to be reversible. (Author)
