No full text146-151Substituted diaryl alkanes are synthesized from benzalazines and acetophenone/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 (1-phenyl) azine and N, N’-bis (1-propyl) azine, respectively

synthesis of 3,5,7-trisubstituted-4H-[1,2]diazepine
5a-p from α,β-unsaturated
1,5-diketone 4 by the condensation
of substituted acetophenones 1 with
1,3-dicarbonyl compound 3 in the
presence of sodium tertiary butoxide has
been described. The intermediate 4
reacts smoothly with hydrazine hydrate catalysed by PSSA in water under
microwave irradiation to yield the product 5
