Abstract

1655 Angew. Chem. Int. Ed. 2005, 44, 1654–1657 www. angewandte. org 2005 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim group of the electrophilic aromatic reagent 3 is also important (Table 1). Thus, the reaction of PhCu (CN) MgCl (1a) with 2-iodobenzophenone (3a) is complete within 30 min at 258C. In the absence of [Fe (acac) 3], less than 5% of biphenyl 4a is observed after 30 min, and a conversion of approximately 54% only is ...
