the subsequent acid promoted transformation of the products were described. In the presence of ZnCl2 and triethylamine, 1 reacted readily with various p-substituted anilines in HMPA under a vacuum of 60–70 mmHg to give the corresponding enaminoaldehydes (2) as a mixture of E- and Z-isomers. Cyclization of 2, without further purification in refluxing toluene, catalyzed by strong acids such as p-toluene

[(phen)2Cu](O2CRF) (1) for the decarboxylative perfluoroalkylation of aryl and heteroaryl halides. Treatment of copper tert-butyloxide with phenanthroline ligands, with subsequent addition of perfluorocarboxylic acids afforded air-stable copper(I) perfluorocarboxylato complexes 1. These complexes reacted with a variety of aryl and heteroaryl halides to form perfluoroalkyl(hetero)arenes in moderate to high
