Abstract
An efficient procedure able to deliver grams of racemic and enantioenriched 2-iodo-N,N-diisopropylferrocenecarboxamide without chromatographic purification was developed. To introduce the halogen, two procedures, one using the nBuLi-TMEDA chelate and one using a lithium amide in the presence of ZnCl2 as in situ trap were developed. Further functionalization by Suzuki–Miyaura and Ullman-type cross-couplings was investigated to access a variety of ferrocene derivatives.
