Simple catalysts formed in situ from iron chloride and a wide range of monodentate and bidentate phosphines and arsines have been screened in the coupling of alkyl halides bearing beta-hydrogens with aryl Grignard reagents. The best of these show excellent activity, as do catalysts formed in situ...

The direct reductive cross-coupling of alkyl halides with aryl halides is described. The transformation is efficient (equimolar amounts of the starting materials are used), generally high-yielding (all but one between 55 and 88% yield), highly functional-group-tolerant [OH, NHBoc, NHCbz, Bpin...
摘要: The title reaction allows the synthesis of a great variety of alkyl aryl sulfones such as (III) via coupling of tosyl chloride (I) with various alkyl halides (II).关键词: sulfoxides, sulfones, sulfenes and derivatives (benzene compounds) ...
