How is 2,6-Difluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzonitrile (CAS: 1003298-73-4) typically synthesized?

2,6-Difluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzonitrile is synthesized via a coupling reaction of the corresponding haloarene with an aryl boronic acid in the presence of a palladium catalyst and a base. Commonly used catalysts include Pd(PPh3)4 and PdCl2(dppf), with an overall yield of around 75-85%. The reaction typically involves B2pin2 as the boronic acid source.
