pyridine derivatives in apolar non-coordinating media with excellent regio- and chemoselectivity, in deep contrast with alkyllithium. With the aim of getting a better understanding of the chemistry behind these promising reagents, we have carried out a joint experimental and theoretical study of the metalation of 2-chloropyridine with combinations of nBuLi and (S)-(-)-N-methyl-2-pyrrolidinylmethoxide (LiPM)
