1. General Information All reactions were carried out in oven-dried Schlenk tubes under argon atmosphere (purity 99.999%) unless otherwise mentioned. Commercial reagents were purchased from Adamas, TCI and Aldrich. Organic solutions were concentrated under reduced pressure on Buchi rotary evaporator. Flash column chromatographic purification of products was accomplished using forced-flow chromatography on Silica Gel (200-300 mesh). 1 H-NMR and 13 C-NMR spectra were recorded on a Bruker Avance 400 spectrometer at ambient temperature. Data for 1 H-NMR are reported as follows: chemical shift (ppm, scale), multiplicity (s = singlet, d = doublet, t = triplet, q = quartet, m = multiplet and/or multiplet resonances, br = broad), coupling constant (Hz), and integration. Data for 13 C- NMR are reported in terms of chemical shift (ppm, scale), multiplicity, and coupling constant (Hz). HRMS analysis was performed on Finnigan LCQ advantage Max Series MS System. ESI-mass data were acquired using a Thermo LTQ Orbitrap XL Instrument equipped with an ESI source and controlled by Xcalibur software. 2. Preparation of Photocatalyst and Redox Active Esters 2.1 Preparation of photocatalyst Ir[dF(CF3)ppy]2(dtbbpy)PF6 The photocatalyst was synthesized according to literature report. 1 (Reference: Lowry, M. S.; Goldsmith, J. I.; Slinker, J. D.; Rohl, R.; Pascal, R. A.; Malliaras, G. G.; Bernhard, S. Chem. Mater. 2005, 17, 5712 5719.) The spectral Data of the photocatalyst is consistent with the literature data. The other photocatalysts (Eosin Y, Ru(bpy)3(PF6)2, Ir(ppy)3 and Mes-Acr) are commercially available. 2.2 Preparation of Redox Active Esters According to literature reports, 2 the redox active esters can be synthesized by the condensation of corresponding carboxylic acids with N-hydroxyphthalimide. S3

The corresponding alkyl carboxylic acid (12 mmol, 1.2 equiv.), N-hydroxyphthalimide (1.63 g, 10 mmol, 1.0 equiv.), and 4-dimethylaminopyridine (61mg, 0.5 mmol, 5 mol %) were mixed in a flask with a magnetic stirring bar. Dry THF or CH2Cl2 (40 ml) (according to the solubility of the carboxylic acids) was added. Then a solution of N,N dicyclohexylcarbodiimide (2.48 g, 12 mmol, 1.2 equiv.) in THF or CH2Cl2 (15 ml) was added slowly at room temperature. The reaction mixture was stirred at room temperature for 6 h. After N-hydroxyphthalimide was completely converted, the white precipitate was filtered off and the solution was concentrated under vacuum. Corresponding redox active esters were purified by column chromatography on silica gel (CH2Cl2 or petroleum ether/ethyl acetate as eluent). 3.

The tube was evacuated and filled with argon (three times). To these solids, N-heteroarene (1.0 equiv., 0.2 mmol) (if liquid) and anhydrous N,Ndimethylacetamide (DMA, 2.0 ml) was added via a gastight syringe under argon atmosphere.

After 3 h, the mixture was quenched with water and extracted with ethyl acetate (3 x 10 ml). The organic layers were combined and concentrated under vacuo.

The tube was evacuated and filled with argon (three times). To these solids, isoquinoline (517 mg, 4 mmol) and anhydrous N,N-dimethylacetamide (DMA, 30 ml) was added via a gastight syringe under argon atmosphere. The reaction mixture was stirred under the irradiation of a 36 W Blue LEDs (distance app. 3.0 cm from the bulb) at room temperature for 5 h. After 5 h, the mixture was diluted with ethyl acetate (120 ml) and washed with brine (3 x 50 ml). The organic layer was dried by Na2SO4 and concentrated under vacuo. After purification by flash column chromatography on silica gel, the product was obtained in 89%. S24
