supports that the arylation is turnover-limited by the oxidativeaddition step and, most importantly, that the oxidativeaddition is accelerated by ethylene glycol, most likely via hydrogen bonding to the chloride at the transition state as shown by DFT calculations. Ethylene glycol thus plays a double role in the arylation, facilitating oxidativeaddition and promoting the subsequent dissociation of chloride
