The decarbonylative coupling of phthalimides with aryl boronic acids provides ready access to a broad range of ortho-substituted benzamides. This nickel-mediated methodology extends reactivity from previously described air-sensitive diorganozinc reagents of limited availability to easily handled and widely commercially available boronic acids. The decarbonylative coupling is tolerant of a broad range

sterically hindered alcohols has been successfully developed via radical–radical coupling reactions enabled by mild and redox-neutral photocatalysis. With alkylsilicates as the radical precursors, a range of primaryalkylradicals bearing various functional groups could couple with a range of phthalimides and activated ketones.

The nickel-mediated cross-coupling of phthalimides with diorganozinc reagents proceeds via a decarbonylative process to produce ortho-substituted benzamides in high yields. In addition to tolerating diverse phthalimide functionality, including alkyl, aryl, and heteroatom containing substituents, this methodology proceeds smoothly with diorganozinc reagents prepared from aryl bromides and utilized without purification.
