Reactions were performed on a 7.5 - 400 MBq scale with 1 μmol of boronic pinacol ester precursor, 0.5 μmol of [Cu(py)4(OTf)2] and 3,4,7,8-Tetramethyl-1,10-phenanthroline stirred in 100 μL of 9:1 MeOH::H2O for 30 minutes at room temperature. RCC’s were calculated by activity trapped on C18 vs starting activity scaled by HPLC chromaogram radioactivity peak integration to account for impurities. RCY was calculated based on activity isolated from preperatory HPLC versus starting activtiy of the reaction.
