Platinum dibromide has been found to promote cage growth and dehydrocoupling reactions between diborane and small, polyhedral carboranes and boranes, yieldind either larger single-cage compounds or bridge-substituted diborane-polyhedral carborane/borane complexes.For the catalyzed reaction of diborane with 1,5-C2B3H5, a cage growth reaction accurs to give the new arachno carborane, 5,6-C2B6H12.For 1,6-C2B4H6 and B5H9, cage growth reactions do not take place but instead the coupled diborane-polyhedral cage species 2:1',2'- and 2:1',2'- are obtained.
