Abstract
The direct tert-butyl group transfer was observed between t-BuBNAH and (η6-arene)Mn(CO)3+ complexes in reflux acetonitrile without a radical initiator, and the corresponding tert-butyl radical addition products were achieved. The substituents on the aromatic ring significantly influence the reactivity and chemoselectivity. The electron-withdrawing group helps to promote the reactions. The radical inhibition experiment indicated that the reaction is probably a radical chain process initiated by single electron transfer.
