[reaction: see text] Iodo- and bromoaromatics bearing sensitive carboxylicester and cyano groups underwent a selective halide-magnesium exchange with isopropylmagnesium chloride at ambient temperature in the presence of bis[2-(N,N-dimethylamino)ethyl] ether to afford the corresponding Grignardreagents. The newly formed reactive Grignardreagents were allowed to react with electrophiles such as trimethylborate

Does formal intramolecular transfer of an acidic deuterium to a site of halogen-lithium exchange show that lithium-halogen exchange is faster than loss of the acidic deuterium? Evidence in favor of an alternative mechanism

They suggest an alternative in which initial loss of the acidic deuterium is followed by halogen-lithium exchange to give a dilithiated intermediate. Deuterium transfer to the site of halogen-lithium exchange then occurs by reaction of the dilithiated species intermolecularly with unreacted N-deuteriated amide. The halogen-lithium exchange is faster than complete mixing of the reactants and can occur
