Abstract

Reaction of lithium derivatives of pyridin-2-ylmethanes, (C5H4N)CRR'- Li+, with mercury(II) iodide results in precipitation of mercury, and formation of symmetrical poly(pyridin-2-y1)ethanes [(C5H4N)CRR']2 (R = H, R' = Ph; R = Me, R' = Ph; R = R' = Me; R = C5H4N, R' = H; R = C5H4N, R' = Me). For [(C5H4N)CRPh]2 (R = H, Me) mixtures of the meso
and racemic diastereoisomers were found. Two of the products, [(C5H4N)CHPh]2 and [(C5H4N)2CH]2, were obtained in high yield, and readily form palladium(II) acetate complexes, Pd(02CMe){(rac-[(C5H4N)CHPh]2} and [Pd(02CMe)2][(C5H4N)2CH]2. The synthesis of 2-(1-phenylethy1)pyridine and a convenient route to bis(pyridin-2-y1)methane are described.
