Organo-Aluminium Compounds. I. Preparation and Properties of Some Phenylaluminium Compounds

Abstract

Reaction of phenylmagnesium halides with aluminium chloride affords a good route to triphenylaluminium etherate and hence to triphenylaluminium, diphenylaluminium chloride, and phenylaluminium dichloride. The molecular weights of these compounds were determined ebulliometrically. Diphenylaluminium chloride and phenylaluminium dichloride form mono-etherates. Possible reactions with benzene, toluene, chloroform, mercuric chloride, and organic halides were examined. A convenient preparation of diphenylmercury is described.
