- En route to molecular bracelets: The synthesis of linear pentacyclic bis(benzodiazocino)benzenes
-
The title compounds, namely dibenzo[b,b']benzo[1,2-f:4,5- f']bis[1,5]diazocines, have been synthesized in a single step in two alternative ways by application of the 'tertiary amino effect': (i) the action of bis-Vilsmeier reagents derived from N,N'-dimethyl-N,N'-diformyl-p- phenylenediamine upon 4-substituted N,N-dimethylanilines, and (ii) the action of Vilsmeier reagents derived form 4-substituted N-methylformanilides on bis(dimethylamino)benzenes.
