Yield:3796-23-4 57 %Chromat.

Reaction Conditions:

with 1,2,3,4-tetrakis(carbazol-9-yl)-5,6-dicyanobenzene;triethylamine in 1-methyl-pyrrolidin-2-one at 20; for 2 h;Inert atmosphere;Irradiation;

Steps:

General procedure A: the photocatalytic hydrodehalogenation of aryl halides.
General procedure: To a 10 mL photocatalytic reactor containing a solution of an aryl halide (0.5 mmol, 1equiv) and 5CzBN (0.01 mmol, 0.02 equiv) in dry NMP (3 mL) was added Et3N (0.8 mmol, 1.6 equiv) under nitrogen atmosphere. The solution was stirred under their radiation of 5 W blue LED for the indicated time until complete consumption of starting material as monitored by GC-MS analysis at rt. The yields were calculated from GC measurements using internal standards.
