Abstract: The 1,4-dihydropyridinate complex [(4-Bn-HBIP)Zn(Bn)], readily available through the highly selective reaction of a 2,6bis(imino)pyridine ligand with dibenzylzinc, contains two distinct reactive centers. One of them is the s-organometallic benzylzinc moiety, which reacts with weak protic acids (e. g., water or methanol) to release the dihydropyridine ligand free. In contrast, the reaction with p-tolualdehyde, a mild electrophile, does not involve the benzylzinc but the 1,4-dihydropyridinate fragment. Even a st…
