Complexes of organoaluminium compounds. Part II. Ammonia, aniline, and diphenylamine complexes of ethylaluminium chlorides

Abstract

Reactions and conductivities in liquid ammonia suggest that the adduct Et₂AlCl,2NH₃ has the structure [Et₂Al(NH₃)₂]⁺Cl^–. Triethylaluminium forms a liquid adduct Et₃Al,2NH₃ and gives a solution of low conductivity in liquid ammonia. Aniline complexes of ethylaluminium chlorides lose ethane on heating, with the formation of the derivatives (R₂AlNHPh)₂ and (RAlNPh)₄(R = Et or Cl), and diphenylamine complexes give derivatives (R₂AlNPh₂)₂. When these react with compounds HX (X = Cl, NH₂, or NMe₂), aluminium–nitrogen bonds are attacked before aluminium–carbon bonds. Amido-derivatives of aluminium are discussed.
