2-Bromo-4-fluorobenzonitrile → 5,2'-Difluoro-5'-nitrobiphenyl-2-carbonitrile

Participants

Reaction Steps

2-Bromo-4-fluorobenzonitrile was coupled to 2-(2-fluoro-5-nitrophenyl)-4,4,5,5-tetramethyl-[1,3,2]dioxaborolane as described in Example 7 part c) to give 5,2′-difluoro-5′-nitrobiphenyl-2-carbonitrile as a black solid: δH (360 MHz, CDCl3) 7.25-7.33 (2H, m), 7.40-7.44 (1H, m), 7.86 (1H, dd, J 9 and 6), 8.35-8.42 (2H, m).
