Yield	Reaction Conditions	Operation in experiment
83%	With dihydrogen peroxide; In water; acetonitrile; at 55℃; for 12h;	General procedure: With the dissolution of substrate (0.4 mmol) in CH 3 CN (2 mL), Pd0/RGO (0.01 g), H 2 O (0.5 mL), and GO (0.01 g) were orderly added into apressure bottle (35 mL). The mixture was dispersed by ultrasound forabout 30 min at 25 C. Then H 2 O 2 (30 wt%, 4 mmol) was cautiously added dropwise. Immediately, the reaction system was heated to 55 Cwith lid closed until the process was fully completed (detected by TLC).Subsequently, Pd0/RGO and GO were removed by centrifuge. Themixture was extracted by deionized water and ethyl acetate. After thelayers were separated, the organic part was washed with deionizedwater, dried with anhydrous NaSO 4 , ltered and evaporated by reducedpressure distillation. Finally, purication of the crude product wascarried out by column chromatography. For 14, 18, 24, 40 (Table 2),excess hydrogen peroxide was added after half of the total reaction time.

Yield	Reaction Conditions	Operation in experiment
56%	In acetonitrile; at 80℃; for 48h;	General procedure: 5,6-Dimethoxy-2-[(pyridin-4-yl)methylene)-1-indanone (0.35 mmol) was dissolved in 4 cc acetone (for synthesis of 5a) or acetonitrile (for synthesis of 5b-o) under refux temperature, and then 1.05 mmol of appropriate alkyl halides was added. The reaction mixture was stirred for 48 h under refux condition. The precipitate was fltered and washed with appropriate solvent. The obtained solid was dried under reduced pressure to aford related compounds.
