A Pd-catalyzed, asymmetric oxidative cross-coupling reaction between ferrocenes and heteroarenes is described. The process, which takes place via a twofold C-H bond activation pathway, proceeds with modest to high efficiencies (36-86%) and high levels of regio- and enantioselectivity (95-99% ee). In the reaction, air oxygen serves as a green oxidant and excess amounts of the coupling partners are not

Dimethylaminomethylferrocenyl lithium and -ruthenocenyl lithium were generated using tin/lithium exchange reactions. The four different metallocenyl lithium compounds were analysed using NMR spectroscopy. The metallocenyl lithium reagents are useful reagents and have been shown to react with MeOD, ClSiMe3 and DMF to give air-stable derivatives. (c) 2005 Elsevier B.V. All rights reserved.
