Novel fluorine-containing 1,10-phenanthrolines having a variety of substituents at the 3-position were easily synthesized in moderate yields by the pyridine-ring formation reaction of N-propargyl-5,7-bis(trifluoroacetyl)-8-quinolylamine with various amines, thiols, and phenols. Unexpectedly. the reactive intermediates 1,4-dihydro-1,10-phenanthrolin-4-ols were isolated for the first time in the reactions with dialkylamines. (C) 2009 Elsevier Ltd. All rights reserved.
