A in situ ring‐closing strategy was developed for the synthesis of N‐heterocycliccarbenenickelcomplexes. The process was carried out in air, and did not require solvent purification. The resulting nickelcomplexes were investigated as catalysts for the coupling of allylic alcohols with aryl boronic acids. A wide range of allylic substrates and aryl acids proved to be applicable to this catalytic

Iron-catalyzed direct reduction of allylic halides with benzylic alcohol was achieved, providing a new, simple, and efficient method for conducting highly regioselective hydrodehalogenation. This method not only features a readily available reductant, an inexpensive catalyst, simple manipulation, and good tolerance of functional groups including nitriles, nitro, esters, and methoxyl groups, it also

[reaction: see text] The cobalt-catalyzed coupling reaction of aromatic halides and allylicacetates proceeds readily under mild conditions in the presence of the appropriate reducing agent to produce allylaromatic derivatives either in pure acetonitrile (aryl bromides) or in an acetonitrile/pyridine mixture (aryl chlorides).
