    Abstract A versatile method for the Suzuki‐Miyaura cross‐coupling of amides using highly active, well‐defined, and air‐stable Pd−phosphine precatalysts is reported. Most notably, the method represents the first example of using practical and operationally‐simple Pd(II)−phosphine precatalysts in the emerging amide bond cross‐coupling manifold. The reactions are efficient at 0.10 mol% loading, furnishing biaryl ketones with high chemoselectivity for N−C(O) bond cleavage. This versatile method enables for the first time to achieve Pd−phosphine‐catalyzed cross‐coupling of amides at ppm loading. This C−N cross‐coupling can be used to efficiently furnish pharmaceutical intermediates by orthogonal Pd‐catalyzed cross‐couplings. We fully expect that operationally‐simple [(PR3)2Pd(II)X2] precatalysts as effective triggers for N−C(O) cross‐coupling will be of broad synthetic and catalytic interest. magnified image
