  • Deprotonative metalation of aromatic compounds using mixed lithium–iron combinations
    作者:Elisabeth Nagaradja、Floris Chevallier、Thierry Roisnel、Viatcheslav Jouikov、Florence Mongin

    The deprotonation of 2-methoxypyridine was attempted using putative (TMP)(3)FeLi prepared from different iron sources. Using iodine to intercept the metalated 2-methoxypyridine, the best result was obtained from FeBr2 (1 equiv) using THF at room temperature: nevertheless, in addition to the expected iodide, the corresponding 2,2'-dimer was obtained (86% total yield). The origin of the competitive formation of the 2,2'-dimer was not identified but mechanisms were suggested to explain its formation. It was observed that the nature of the electrophile employed to trap the 3-metalated 2-methoxypyridine has a strong impact on this dimer formation, the latter being favored using iodine (35% yield), but also benzophenone (28%), benzoyl chloride (22%), methyl iodide (27%), allyl bromide (15%), benzyl bromide (41%), and tetramethylthiuram disulphide (36%); for this reason, the yields of the expected derivatives were only 51, 15, 62, 0, <5, 18, and 0%, respectively. In contrast, using aldehydes readily led to the expected pyridine alcohols without dimerization (59% yield using 3,4,5-trimethoxybenzaldehyde and 66% yield using pivalaldehyde). 2,6-Dimethoxypyridine (in 68% yield), anisole (47%), 2,4-dimethoxypyrimidine (50% at C5 and 3% at C6), 2-fluoropyridine (64%), and thiophene (49%) were similarly converted into the corresponding alcohols after subsequent trapping with pivalaldehyde. Using iodine to trap the 2-metalated anisole did not lead to dimer formation, and 2-iodoanisole was isolated in 71% yield. (C) 2012 Elsevier Ltd. All rights reserved.
