9,10-Dihydroacridines are frequently encountered as key scaffolds in OLEDs. However, accessing those compounds from feedstock precursors typically requires multiple steps. Herein, a modular one-pot synthesis of 9,10-dihydroacridine frameworks is achieved through a reaction sequence featuring a selective ortho-C alkenylation of diarylamines with aryl alkynes followed by an intramolecular hydroarylation of the olefin formed as an intermediate. This transformation was accomplished by virtue of the combination of hexafluoroisopropanol and triflimide as a catalyst that triggers the whole process.

Spiroacridans 4, 5 are easily obtained by condensation of diarylamines 1, 2 and cyclic ketones 3.NMR and UV spectroscopic investigations show that the 9-arylsubstituted spiroacridans 4d, e and 5d exist in a twisted (boat) conformation with a pseudoequator
