Preparation and properties of some co-ordination compounds formed between aluminium alkyls and their derivatives and ligands from groups V and VI

Abstract

Reactions of the dimeric aluminium alkyls, (AlR₃)₂ where R = Me or Et, and the alkylaluminium compounds, (R₂AlX)₂ where R = Me or Et, X = F, Cl, Br, I, CN, NMe₂, NEt₂, SMe, or OEt, and (RAIX₂)₂, where R = Et, X = Cl or I, with various ligand molecules, e.g. NMe₃, C₅H₅N, PMe₃, Et₂O, and Me₂SO, have been investigated. The properties of the adducts are described, and the relative acceptor properties of the different aluminium compounds are compared.
