Yield:591-17-3 72%
Reaction Conditions:
with bis(1,5-cyclooctadiene)nickel (0);tetrabutylammonium bromide;4,4′-di-tert-butyl-2,2′-bipyridine in 1,4-dioxane at 20; for 36 h;Schlenk technique;Glovebox;Irradiation;Sealed tube;
Steps:
14 Preparation of 1f(X1=Br, R1=3-Me)
In the glove box, weigh the dry catalyst Ni(COD)2 (5.5mg, 0.02mmol, 10mol%) and dtbbpy (6.4mg, 0.024mmol, 12mol%) into a 10ml dry and clean schlenk tube equipped with a stirring bar, add 1,4-dioxane (1 ml), stirred at room temperature for 10 minutes. Weigh tetrabutylammonium bromide (128.8mg, 0.4 mmol), corresponding 2f (X2=I, R1=3-Me) (23.6mg, 0.2mmol), then add 1ml CPME, seal and irradiate with blue light at 455nm The reaction was carried out at room temperature for 36 hours, and the yield was 72%. 1f
