AbstractA selective and operationally simple iron‐catalyzed cross‐coupling of aryl chlorides with alkylmagnesium halides has been developed. The reaction tolerates various functional groups and exhibits high chemoselectivity even in the presence of aryl bromides. Mechanistic studies indicate the essential role of the olefin substituent for substrate activation. Competing polymerization and reduction are effectively suppressed.magnified image

This invention provides a process for preparing a phosphinoarylalkene and polymers thereof comprising reacting an arylalkene bearing a leaving group attached to a carbon atom of the aryl ring, or a polymer thereof, with a phosphine in the presence of a Group VIIIa metal catalyst. The polymer resins may be used as metal sequestering agents or phase transfer catalysts, or as ligands for transition metals and supported catalysts.

We report an operationally simple protocol for the catalytic α-deuteration of styrenes. This process proceeds via the base-catalyzed reversible addition of methanol to styrenes in DMSO -d6 solvent. The concentration of methanol is shown to be critical for high yields and selectivities over multiple competing side reactions. The synthetic utility of α-deuterated styrenes for accessing deuterium-labeled
