Synthesis of functionalized diaryl alkancs from azines

Manih, Rudolf M.,Myrboh, Bekington

experimental part, p. 146 - 151 (2009/12/01)

Substituted diaryl alkanes arc synthesized from bcnzalazines and acctophenone/propiophenone azines via Friedel Craft's reaction with substituted mono- and poly-nuclear aromatic hydrocarbons. Diaryl methanes/ethanes and propanes are obtained by reaction with benzalazine, N,N'-bis (I-phenyl) azine and N, N'-bis (I-propyl) azine, respectively.
