Various functionalized aryl and alkenyl manganese halides have been prepared from the corresponding aryl and alkenylhalides according to a one-pot procedure: lithium-halogen exchange at low temperature then Li-Mn transmetallation. (C) 1997 Published by Elsevier Science Ltd.
New Efficient Nickel-Catalyzed Cross-Coupling Reaction between Two Csp<sup>3</sup> Centers
carbonyl group, cyano group) in an alkyl halide facilitates its cross-coupling reaction with various diorganozincs in the presence of Ni(acac)(2) (7.5-10 mol % in THF/NMP mixtures). These results were used to develop a new general cross-coupling reaction between functionalized diorganozincs and alkyliodides using m- or p-trifluoromethylstyrene as a reaction promotor and Ni(acac)(2) as a catalyst (7.5-10

A manganese-catalyzedelectrochemicaldeconstructivechlorination of cycloalkanols has been developed. This electrochemical method provides access to alkoxyradicals from alcohols and exhibits a broad substrate scope, with various cyclopropanols and cyclobutanols converted into synthetically useful β- and γ-chlorinated ketones (40 examples). Furthermore, the combination of recirculating flow electrochemistry
