with dipotassium peroxodisulfate;silver carbonate in fluorobenzene;water at 60; for 0.5 h;Solvent;Reagent/catalyst;

Steps:

1-7 Example 7:

0.049g (0.4mmol) phenylboronic acid 1a, 0.029g (0.2mmol) dimethyl butyne dicarboxylate2a,). 016g (0.006mmol) silver carbonate, 0.216g (0.8mmol) potassium persulfate, 2mL fluorobenzene and water (3: 1)In a 10ml thick-walled pressure-resistant tube, under 60C in an oil bath, the reaction was magnetically stirred for 0.5h, and the reaction progress was monitored by TLC. End of reactionAfter that, column chromatography separated to obtain 9,10-phenanthrenedicarboxylic acid dimethyl 3a as a white solid, 41 mg, and the yield was 70%.
