摘要

The corresponding “pseudobase” Δ2-1, 5-diketones (8) and (14) afford dihydrochromenylium (9b) and tetrahydro-xanthylium monofluorides (15). These convert aryl- and heteroarylamines into dihydroquinolinium (10) and tetrahydro-acridinium (16) monofluorides which at 130–250° give the deaminated arenes and heteroarenes (average overall yield 60%).
