The above reaction procedure used for 2-iodophenol was followed. The reaction was also faster, being again complete before the first sample for gc analysis was withdrawn after 1 h 50 min reaction time. The amount of phenylboronic acid pinacol ester was about that found in the 3-iodophenol reaction. The reaction in which 4-bromophenol is used as substrate is slower but does go to completion. Pinacolborane prepared in situ from the dimethylsulfide adduct of borane can also be used with both the 4-bromophenol and 4-iodophenol.
