a Obtained unexpected bromide product 6. b Bromine trapping experiment. c The degradation reaction of Na2-eosin Y. aReactions performed on 0.20 mmol scale with dimethyl terephthalate as an internal standard (1H NMR yield). bYield relative to 1,3,5-trimethoxybenzene. cReactions performed on 0.06 mmol scale with dimethyl terephthalate as an internal standard (1H NMR yield). dYield relative to α-terpinene. NR no reaction.
