Boron-hydrogen compounds and adducts of these containing metals                 (metalloboranes) or carbon (carboranes) exhibit unusual types                   of chemical bonds which are of considerable interest to                         theoretical chemists. These compounds are also of growing                       importance as precursors to new solid state materials. This                     project is a continuing investigation of the mechanisms of                      structural transformations of boron compounds. The chemical                     knowledge gained will guide the development of new synthetic                    routes to metalloboranes and new applications of these                          molecules in other areas of chemistry.                                                                                                                          The mechanisms of reactions and rearrangements of model borane                  and heteroatom borane clusters will be determined using                         stereospecific boron isotopic labeling as a primary diagnostic                  probe. Examples include rearrangement studies of                                closo-carboranes and nido- and arachno-hexaboranes, mechanistic                 studies of polyalkylation of boranes, and characterization of                   long lived intermediates formed during the reduction of boron-                  halogen bonds by trialkyltin hydrides. Group V heteroatom-                      borane clusters will be prepared and their chemical,                            spectroscopic and structural features established. The scope of                 reactivity of several classes of metalloboranes including some                  containing Zn and Mn will be determined. The syntheses of high                  boron content polymers will be developed for possible                           applications in energy storage and solid state materials.
