WebMay 22, 2012 · Abstract. [Ir (cod)2]BARF [BARF = tetrakis (3,5-trifluoromethylphenyl)borate] catalyzed the directed alkenylation and alkylation of ferrocenes to form a variety of tri- and disubstituted ferrocenes. WebDec 17, 2007 · The iridium-catalyzed oxidative esterification reaction can be explained, as shown in Scheme 1. A large excess of methanol feasibly converts [IrCl (cod)] 2 to its iridium methoxo intermediate a by the assistance of K 2 CO 3. Benzaldehyde coordinates to the intermediate to give the species b as the carbonyl function being activated by the metal. rayhan virgin investments
