Exploration Of Low-valent Aluminum Cluster And Synthesis And Characterization Of Diazaphospholide Aluminum Complexes

This thesis mainly contains two sections:（1） exploration of thesynthesis of low-valent aluminum cluster;（2） preparation of aluminumcomplexes bearing diazaphospholide ligand.（1） With electronic and steric effect, reaction of NHC （IPr） and AlI₃produced IPr AlI3monitored by¹H NMR. Reduction of IPr AlI₃withKC₈、K or K-Na alloy was performed at varied temperature andsolvents, and so on. However, the products turned out to be oil afterwork-out.（2） Reaction of [3,5-tBu₂dp]K and AlCl₃in ratio of1:1and3:1respectively, afforded aluminum complexes which werecharacterized by¹H NMR,¹3C NMR,³1P NMR and XRD. The presentwork is potential for the synthesis of or the research on alkynylaluminium and hydroaluminium compounds.
