Abstract
In the present work, hydroalumination reactions were carried out successfully on nitriles and mono-substituted acetylenes in the synthesis of imidoalane and carbaalane cluster compounds. A possible reaction pathway involved in the synthesis of these compounds was discussed. The hydrides on imidoalane cluster were substituted with halides (Cl and Br), acetylides (PhC≡C and C3H5C≡C), alkyls (Me and Et), and sulfide (PhS) by carrying out reactions with nucleophilic reagents. Hydroalumination reaction on trisaluminum acetylide was described, an alternative method for the synthesis of carbaalane. The reactivity of the Al H bonds of the carbaalane was studied in the presence of phenyl- and ferrocenylacetylene. Ferrocenylnitrile and ferrocenylacetylene underwent hydroalumination reactions to generate heteronuclear imidoalane and carbaalane. The ferrocene containing molecules were also incorporated on both the clusters and their electrochemical behavior was studied in detail. In addition, the reactivity of Al H bonds of the β-diketiminato stabilized aluminum dihydride was explored in the presence of methylhydrazine and tert-butyl hydrogenperoxide.
