Hikawa, Hidemasa published the artcilePalladium-Catalyzed Dehydrogenation of Benzyl Alcohols for Construction of 2-Arylbenzimidazoles ”On Water”, Formula: C19H14N2, the publication is Asian Journal of Organic Chemistry (2018), 7(2), 416-423, database is CAplus.
An ”on water” synthetic strategy for the selective construction of 2-arylbenzimidazoles involving the dehydrogenation of benzyl alcs. by a π-benzylpalladium(II) system was developed. This simple oxidant- and base-free protocol was achieved under mild conditions in an atom-economic process from o-phenylenediamines and benzyl alcs., affording the desired products in moderate to excellent yields. Notably, the ”on water” protocol was essential for achieving this synthetic method in this catalytic system.
