Boron hydride derivatives. Part XI. Iodination of decaborane

Abstract

Hillman's work on the iodination of decaborane has been extended to include the reaction between decaborane and iodine chloride in the presence of aluminium chloride. The yields of products are consistent only with an electrophilic substitution mechanism. It has also been shown that deuterium migration occurs in µ,µ′,µ″,µ‴, 5,6,7,8,9,10-decadeuteriodecaborane under the influence of hydrogen iodide. Hillman's “5-iododecaborane” is in consequence 1-iododecaborane.
