A base-free, nickel-catalyzed decarbonylative coupling of carboxylic acid fluorides with diboron reagents selectively affords aryl boronate esters. The method is applicable to various (hetero)aryl carboxylic acid fluorides as well as diverse diboron reagents. The acid fluorides can also be generated in situ directly from carboxylic acids.
