                    Coordination Chemistry of Aluminum: Molecular Alumoxanes and

                                      Aluminum Chalcogenides.

   

   

   The preparation of functionalized molecular alumoxanes, [{LAl(X)(μ-O)}[2]] (X = H, OH,
   SH, SeH; L = [HC{MeC(NAr)}[2], Ar = 2,4,6-Me[3]C[6]H[2]]) and the related aluminum
   chalcogenides [{LAl(EH)(μ-E)}[2]] (E = S, Se) (Figure 1) will be discussed together with
   their reactivity in the formation of inorganic rings. The effects of the different chalcogens
   on the formation of the final products will be demonstrated. Furthermore, reactivity studies
   of selective compounds with small molecules will be presented. In the second part, we will
   focus on the preparation of different aluminum complexes of
   bis(diphenylchalcogenophosphinoyl)triazoles [Ph[2]P(E)][2](C[2]N[3])H (E = O, S, Se). Neutral
   and ionic complexes can be obtained from these reactions depending on the aluminum reagent.
