Notes:
Aldehydes, when added to mixtures of ethylaluminum dichloride and titanium trichloride under pressure of propylene, have been found to promote either propylation of benzene or stereospecific polymerization of propylene. Selectivity between the two reaction paths is influenced by the molecular structure of the aldehyde. Most aldehydes promote propylation of benzene to cumene and higher isopropyl benzenes. Propylation occurs with or without titanium trichloride present. Substituted aromatic aldehydes with three or more alkyl substituents promote stereospecific polymerization of propylene. Both reactions are dependent upon the ethylaluminum dichloride/aldehyde molar ratio.
