Yield:1842-38-2 98%

Reaction Conditions:

with eosin Y disodium salt;N-ethyl-N,N-diisopropylamine in acetonitrile at 20; for 20 h;Schlenk technique;Inert atmosphere;Irradiation;Green chemistry;

Steps:

General Procedure for Synthesis of.

General procedure: The corresponding pyridinium salt (0.4 mmol, 1.0 equiv), Eosin Y (0.48 mmol, 0.12 equiv) and Diselenides (0.48 mmol, 1.2 equiv) were weighed into a Schlenk tube containing a magnetic stirring bar. The tube was evacuated and backfilled with Argon three times. MeCN (2 mL, 0.2 M) and DIPEA (0.8 mmol, 2.0 equiv) was added and the reaction was stirred under irradiation with 24 W blue LEDs for 20 h at room temperature. the solvent was removed under reduced pressure. The crude product was purified by column chromatography over silica gel to afford pure products.
